Cutting Boards...Polymer vs Maple

Years ago the local health department came through my kitchen and told me I should think about removing all of the wooden cutting boards that we had on our line. " Plastic is better, easier to clean" the inspector said. I always resisted for a few reasons. First, I was in busniess and we didn't see the need to replace anything that wasn't broken unless there was a monetary benefit. Second the wooden cutting boards were nicer on the knives. I find the plastic boards take the edge off faster, especially when doing a lot of chopping, such as mincing garlic or parsley. Third was simply aesthetics, the wooden boards looked warmer, more "homemade" so if we took a photo of a rustic dish with a wooden board it just looked better. So which is best?

Today I work on large plastic tables in the meatroom at the CIA. They are used by three seperate classes daily. There are thousands of little nicks and dings and a few larger saw cuts from the many classes that have used them over the past 5 0r 6 years, since they were last replaced. We wash them and sanitize them each night, then allow them to air dry in a cold room.

So which is better? First lets talk about what they actually are. Plastic cutting boards are made of polyethelene and can be made in a variety of thicknesses. Over time they get nicks and cuts in them which can harbor bacteria, making them difficult to sanitize. There are some that claim antibacterial surface but the effectiveness of this is questionable. Most carry a warning stating "This product does not protect against bacteria". Once the antibacterial board is cut into bacteria will also be found in it. Plastic boards can be planed and resurfaced if thick enough, getting rid of all the nicks. Cleaning plastic can be done in a dish machine if small enough to fit which sterilizes the surface. Another aspect of plastic boards is they can be colored to designate uses; yellow for poultry, green for vegis, white for meat etc. Super thin plastic cutting mats can be used for small portable cutting and these can also be washed in a machine. Plastic boards can be sanitized with harsh chemicals such as bleach and then rinsed thoroughly whereas wood will absorb the flavor of the chemical.

Wooden cutting boards are made of hardwoods that have a tight grain. Maple is most typical, hickory is possible also, teak and other tropical woods are found but very expensive. Oaks' grain is too wide enabling moisture to penetrate. Pine and other fir trees are way too soft and fragile. Bamboo is cut and layered to make a very hard board that resists cuts but can dull knives somewhat. Bamboo boards can be light and thin and very easy to clean. Wooden boards can be cleaned with abrasive scrubbers such as steel wool which actually take a tiny layer off, healing the board's cuts. Maple boards resist bacterial growth and are found to be safer than a over-used plastic board but wooden boards cannot be allowed to be continually moist or soaked in sinks. They can split and mold can form in the cracks. Wooden boards can be planed, also to resurface. They must be kept dry and may require an occassional conditioning with mineral oil. I have seen old school butcher shops pour salt on their boards every night and then wipe it off in the morning to kill any harmful bacteria. Small wooden cutting boards can be sanitized in a microwave. Wood is also a "green" renewable resource as opposed to plastic.

Another type of board is made from rubber. Two inch thick rubber boards are expensive but feature some of the best of both worlds. They can be sanatized like plastic but won't dull your knives as easily. Rubber is also renewable. They can warp but they also can be heated in an oven to be reshaped. Rubber boards "heal" like wood so the small cuts seal back up keeping it free of bacteria harboring nicks.

When chopping with the cleaver, plastic and rubber boards will be damaged. Normal wooden boards will chip and damage also but the maple "chopping" block is designed for it. The grain is set so the cleaver is chopping down into it as opposed to across.

Whatever board you choose its imperative that it is cleaned correctly and replaced when worn. Each type has its advantages and disadvantages and inital cost plays a part in the decision. I welcome any comments on this and ideas from you.

Butcher Skills for Restaurant Chefs

A meatcutter in a large packing plant can fabricate an enormous amount of meat in a single day. They have the advantage of the "assembly line" arrangement with all of modern techniques and equipment. For instance, the task of boning a leg of lamb and tying it into a roast is done over and over by a single person working off of a moving conveyor belt. The cutter doesn't need to carry anything or move from his or her spot. The its a simple 1-2-3 step proceedure, pull the leg off the conveyor belt, bone it out and throw it back on, and then the roast is formed and netted by someone else. On larger cuts, such as beef, the task may be aided by hydrolic pullers and tools specifically designed to reduce stressful labor and increase speed of fabrication. The result is a product that is cut accurately to industry specs that is standardized and available from purveyors with regularity. The same goes for portion cut items. Steaks and chops are cut on machines that can regulate thickness and weight and done in huge volume so the processor can pick out all of the like-sized portions for accuracy. You can buy a perfect 10 oz striploin steak over and over.

So why would a chef decide to do any fabrication in house? There is no way to match the speed of the large plants and they would need to pay someone to do it. But the restaurant chef that has some butchery skills has an advantage over those that don't. They can custom cut things that are outside the norm such as instead of simply boning the leg of lamb they can french off the end of the shank, remove all other bones, stuff the interior and then tie it to create a look that is unique. Meat cutting, especially on the small custom restaurant or meat market level can go in directions that a large processor can not possibly do. Other examples are chefs who dabble in curing meats. A ham, custom partially boned in the true prosciutto style, leaves the femur and shank intact but the aitch bone removed except for a little corner of it to protect the interior from mold. You can't buy this from a large processor. All sorts of little tricks and custom ideas can be done to maximize yields, create unique looks, convert tougher cuts to tender all by butchery skill.

Another situation invloves chefs that want to sell meat from a small local processor. Most small processors cut meat from local farms but cut for retail freezer orders. They focus on quick volume band saw work which may not be good for a restaurant. Today we find some chefs buying the entire primal cut and breaking it down themselves. This enables them to utilize all of the trim, bones and even fat to make a large variety of sauces and dishes that wouldn't occur if they purchased pre-cut items. This cutting requires a lot of skill and time. There is no assembly line. Meats need to be cut on a large table instead of off the hook. Meats are out in a warmer environment than in a meat plant so spoilage is an issue. Crosscontamination can occur if proper care isn't taken. But the end result can be a taste and texture that is as signature as a fine pastry or a great sauce. A restaurant that custom cuts their meat can use the fact on the menu or in advertising. Even an inexpensive bistro can offer an in-house ground burger that is made from whole muscle cuts rather than buying pre-ground beef that may have contamination.

I must admit that I am partial to chefs cutting some or all of their meat in-house, afterall I have trained a lot of them. I also realize in many situations such as very high volume hotels or casinos can't possibly do all their fabrications but there are often ways to save money or create new presentations by custom cutting.

Buying local:Right way, wrong way, NO way!

At the CIA we are buying some local meat for our St Andrews Restaurant. We have found that the Hudson Valley has a large variety of meats raised by farms within 60 miles of our location including, beef, lamb, pork, poultry and even some veal. We have been getting beef from two producers Meiller's in Pine Plains and Rykowskis in Rosendale NY. Both have quality beef breeds, Meiller's has some very nice Angus and Rykowski has Hereford. These livestock are on pasture and are supplemented with corn and fermented silage which fattens them up. Meillers has been reaching high choice marbling scores and Rykowskis are reaching at least select levels. We have aged the striploins and rib eyes from both with great success. With both of these farmers, sometimes the marbling is high, sometimes low but the cattle are young enough to still have fine fibers and therefore a quality meat.

I have experienced some very high quality strictly grass fed beef from a grower in mid state NY that had the distinct grass flavor but also some marbling. The rib eye we sampled was tender and savory. An innovator in this field is a company called TallGrass in Kansas. http://www.tallgrassbeef.com/ Bill Kurtis, ownner, has a philosophy of raising quality beef on pasture and is gaining some market share. Jo Robinson, the pasture feeding advocate, describes a good pasture fed beef farmer as more of a grass farmer, growing a high quality grass as the main food stuff.

In past posts I wrote about Scottish Highland cattle and their ability to fatten on grass and forage. They have a very fine fiber and produce a lower fat but quality meat. They are not typically raised commercially due to their excessive furry coat and very large horns but there are numerous farms throughout the US that do raise and sell their meat. NY state has over 35 farms registered as raising Highland cattle and many more in New England and Pennsylvania.

Recently we recieved a pasture raised Highland that was raised in Rhinebeck NY. It was not what I expected. The beef had absolutely no fat on the exterior and no marbling at all!. Surely this was not inducative of what this breed represents. It was by no means quality, but not because of the breed but how it was raised. The term "grass fed" doesn't simply mean the animal is allowed to roam a pasture and eat down all the grass, even though this is what, many people believe. High quality grass fed is placed on ripe fresh grass and then moved from pasture to pasture to insure the animal gets plenty of nutrition, even to the point of marbling. I have tasted numerous grass fed steaks that had marbling and might have graded low choice. I understand that Highland cattle develop less fat and maybe it was that it was an extermely hot time of year but this was a waste.

Another issue was the lack of USDA inspection. Farmers can be exempt from USDA inspection if they are selling directly to the end user. The meat must be stamped "NOT FOR SALE" as was the case on or carcass. I called the NY Ags and Markets dept. to confirm my suspicion. This meat was not legal for sale in a restaurant. But what about using it for demo in a school setting? The meat would have been consumed by students, therefore it would be considered part of their meal plan and in effect would have been sold to them, making it illegal.

The third issue was the price. I know that locally grown, fully pastured beef is going for a high price these days but this 500 lb carcass was over $3,000! I recognize the need for farmers to recoup their investment but this seemed excessive, especially considering the quality of the meat.

Lessons learned? Know your farmer if buying local. Local does not simply mean better! Be sure to purchase inspected meat if selling it in a restaurant or shop. Uninspected farmer's market meats are ok for home cooks that are not re-selling but a chef needs to be more cautious.

This post by no means was meant to discourage the use of quality grass fed beef or heritage Highland cattle but there is a right way and a wrong way to buy local meat and there was NO way we could use this example.

Over grazed pasture.

Angus Veal is Real!

Veal in the US is traditionally from Holstein cattle due to the fact that it is primarily the male offspring that aren't usable on the dairy farm. The Holstein can be raised as beef and this is done often but the meat quality is not as desired as from other "meat" breeds such as Angus or Charolais.

About three weeks ago we had the chance to break down an entire veal carcass in class. Chef Soileau purchased it from Hackett Farm, Salt Point NY. It was unique in that it wasn't the typical Holstein veal that we find in most markets, its was from Angus. The idea of taking a higher quality meat breed and harvesting it much younger enabled us to compare these veal. The carcass was a true milk fed product and the calf had been feeding on real milk for its early life but had started to eat some pasture. It was about 4 1/2 months old and weighed about 225 for the cleaned carcass, which is smaller than most of the veal that is found in the commercial marketplace today.

Chef Dave Kamen divided the carcass into the primal cuts and then my class turned everything into roasts , stew, cutlets, chops and grind. We left the breast whole for stuffing.

The color was a little more red than most veal we get but the conformation was very good. The Angus traits could be seen in the nice oval chops. We had aged it for about 8 days so it was nice and firm when we cut it. Most veal is packed about a day after slaughter and it never gets a chance to set up properly. The aging improved its flavor. When I called Chef Soileau about what he thought of it he said " Oh Man! Butter! Best ever! "

Don't expect the veal industry to jump on this band wagon though. Angus calves are very costly as a feeder stock and it may not make economic sense to raise Angus for veal but it was a delight to see this meat and taste the end result.

Wagyu Woes

The other day I assigned some research for my class after reading some disturbing news reports about Wagyu beef in Japan. The assignment was basic, write about the situation in Japan and also find out about Wagyu production in Australia. Being a casual sidebar assignment I allowed a simple web source to be the citation. This is what Maxim Pettersen handed in....

What happened to Wagyu in Japan?:

Japan's prized Miyazaki beef is under threat from the country's first outbreak of foot-and-mouth disease since 2000, which has spread to more than 100 frams. Foot- and- mouth disease is a highly contagious and sometimes fatal viral disease of cloven-hoofed animals such as cattle, water buffalo, sheep, goats, and pigs, as well as antelope, bison and other wild bovids, and deer. The disease is highly transmissible and the icubation period has a range between 2- 12 days. It is characterized by high fever, blisters inside the mouth, drooling, blisters on the feet that cause lameness. The outbreak in Japan has forced the slaughtering of 49 seed bulls, leaving only six prized seed bulls that breed the tender beef from Miyazaki. Prime Minister Yukio Hatayama has pledged 100 billion yen ( $1.08 billion dollars) to assist farmers who are expected to lose 16 billion yen from slaughtering their livestock. The foot and mouth otbreak, also known as FMVD, was detected on April 20th, and has spread to 111 farms in Miyazaki, Japan's south, involving more than 85,000 cattle, and pigs. Fears are growing that it may spread beyond Miazaki. http://www.sbs.com.au/news/article/1259427/Foot-and-mouth-threatens-Wagyu-beef

Wagyu Production in Australia:

Australia received its first Wagyu genetics from a Wagyu female in 1990. Frozen semen and embryos have been available since 1991 and there have been numerous imports of live purebreds into Australia, and specifically in 1997, the first fullbloods came to Australia. The Australian Wagyu Association is the largest breed association outside of Japan. Both Fullblod and Wagyu Croos bred cattle are farmed in Australia for domestic and overseas markets. The Wagyu cattle represent only 100,000 of the 28.8 million cattle in Australia, however takes up 40% of the Australian feedlot space in a 12 month period. The FMVD outbreak that has banned the export of Wagyu cattle in Japan, has increased the demand for Australian Wagyu producers, and some producers hope to double their exports to overseas markets such as the U.S. http://www.weeklytimesnow.com.au/article/2010/06/07/193891business-news.html

Kiwi, Papya and Sharp Pointy Things

Last class we decided to test out some meat tenderizing techniques. A while back I had purchased a Jaccard knife and we use it regularly to tenderize tougher veal cutlets, skirt steaks etc. I tell the students about how it is used on a larger scale by many portion cutting processors and has its attributes for introducing marinades deeper into the meat. It also has come under some scrutiny because of the problem of possible crosscontamination of bacteria into a steak type cut that will be cooked to medium rare or less. http://www.ars.usda.gov/research/publications/publications.htm?seq_no_115=250404

The Jaccard has its place in the kitchen and if used and cleaned properly it can be a good way to get cuts that are sitting on the tenderness "fence" to be made more palatable.

On to our testing. We chose to use the Beef Sirloin Flap which is palatable but often a little tough to be served as an unsliced portion. While the Jaccard works well we decided to try some other techniques that will do the job. We experimented with two other methods, applying Papya and Kiwi fruit to steak cuts. We peeled and sliced both fruits and messaged them into two separate steaks and left them loose wrapped over night. The third steak was simply Jaccarded without any marinade or spice. When it came time to cook them we seasoned all three with salt and pepper, lightly so as not to interrupt the naturally occuring tastes. They were cooked to medium rare individually in a heavy black skillet with a little rendered beef fat in the pan to prevent sticking.

The results? All three methods were effective in tenderizing the meat with the two fruit methods differing somewhat from the Jaccard. The mechanical method worked well but without any marinade, it turned out a little dry. It also cooked faster due to the ability for heat to "chimney" up the tiny holes that were pierced through it. Moisture had leaked out of the meat but it was still palatable.

The Papya worked well but left a lightly sweet flavor and carmelized quite a bit in the pan. Papya contains a protease enzyme, papain, which chemically breaks down the collagen muscle fiber sheaths within the muscle. Kiwi fruit also contains protease enzymes and the effects from placing it over the steak was also very effective. The Kiwi didn't have quite the same amount of sweetness but did leave a residual flavor. Both fruits broke down the fibers about equally resulting in a steak that could be cut with a regular steak knife with ease. At 24 hrs we did not experience a "mushy" texture that can happen when steaks are left too long. In a previous test we left a steak with Papya over a weekend and it became overly tenderized and very soft which resulted in an unatural texture. The meat fibers had basically disolved.

None of the three in this test were disagreable in taste but there were certainly differences. The question is how would they be used in the kitchen? If you are trying to maintain the original flavor of the meat, the mechanical system is probably best. There is no added flavor. If looking for an ingredient that will add some flavor and can do a nice job tenderizing these two fruits worked well. Other fruits containing protease enzymes are figs, pineapple, and honey dew melon. All of these will do the job but will also add flavor. Be sure not to over marinate due to the mush factor. A half of a kiwi can be enough for about 4 lbs of meat and it is easy to overuse it. http://www.thekitchn.com/thekitchn/tips-techniques/tip-tenderizing-with-kiwi-011683

Steam Bath

The other day we were cutting beef top rounds into trimmed roasts in class. Half the class was cutting Certified Angus and the other half were using regular IBP Choice XT. XT stands for Extra Trimmed, I believe. I was asking the class to observe any differences between the two, hoping for some comments on the fat trim level or marbling scores. Instead what they noticed the most was the fact that the CAB had a discoloration on the exposed meat and the XT did not. The CAB top round was a basic untrimmed subprimal which was packaged "as is" when taken off the bone. The XT had the cap fat trimmed to 1/4 inch and the discoloration trimmed off. The grayish tint is not caused by any spoilage or pathogen, it is the result of the carcass steam cleaning process.

Steam cleaning takes place in most large beef processing plants today. It is typically a combination of whole carcass washing with water, hand held steam vacuums during evisceration, and a steam pasteurization cabinet for the whole split dressed carcass. Often carcasses are also sprayed with an organic acid to further guard against pathogens. IBP, owned by Tyson, developed the "Triple Clean" method after a huge beef recall of about 750,000 lbs in 1998. This method applied the hand held vacuum steamers and a huge car wash type steam cabinet on their line for the first time. The end result is a cleaner beef but also a sort of pre-cooked layer on some exposed cuts. The top round, flank steak, skirt and hanger steaks, and sometimes the tenderloin can be found with some slight discolorations caused by the steam. Most other cuts are protected by the exterior fat or bone coverage.

The basic reason for this extra cleaning is E. coli O157:H7 which is found in the fecal matter on the outside of the hide or in the intestinal tract. The speed of the processing and the fact that cattle often arrive with contaminated hides and intestinals makes extra cleaning a safer alternative. But all this extra cleaning is expensive and errors can be made.

Another idea is to reduce the amount of E coli before the animal leaves its feedyard. This can be done a couple of ways. First by cleaning out excessive waste so animals are cleaner and dryer when they leave. Many times, especially in rainy summer months, cattle are standing in muck. Some feedyards are a lot better about this than others and there should be a standard.

Another is to feed the cattle hay or barley a few days before slaughter. This causes a change in the intestine that helps to reduce the E. coli dramtically. This is not to say that the animal should be on pasture or not ever grain fed but simply creating a dramtic switch from a corn ration to hay for the last few days could reduce E.coli counts significantly. http://www.horizonpress.com/cimb/v/v11/67.pdf So why aren't most large processors demanding this switch to keep the cattle cleaner? Maybe its a weight loss issue or a cost that makes this impractical. But the cost of the steam cleaning must be high too.

Other interventions, such as Lactobacillus-based direct-fed microbials, vaccines and irradiation are also being suggested. Diet introduced probiotics can reduce E. coli. http://www.ncbi.nlm.nih.gov/pubmed/12747680 There is a vaccine for it too. But both of these add extra expense. One company developed a vaccine and spent $15,000,000 in doing it ( also $50,000,000 in advertising it!) http://www.npr.org/templates/story/story.php?storyId=6138682

The goal of irradiation is to "pasteurize" the carcass. This would eliminate a lot of pathogen risk and contrary to popular sentiment, it wouldn't glow in the dark. My issue with this method is when a meat is irradiated will the good flora that enables part of the flavor of a proper dry aging be destroyed? How much vitamin content will be lost? Also if the goal of irradiating is to eliminate E.coli by sterilizing it and E.coli is typically found in fecal matter then are we to accept sterilized fecal matter as a food? Not my idea of a fine dining experience.

Steam cleaning is a good idea and it has made our meat supply safer. Hay, you know that dried stuff grown in open fields, seems like a good idea too. There is no one solution but there are some that make more sense than others.
