Silverskin Blues

The other day we had to denude 15 boneless pork loins to make a bunch of clean 4 oz. cutlets. Part of the process is to peel off the silver collagen on the outside of the loin. First I trimmed off the thin fat layer and then carefully inserted the knife under the collagen and peeled it off in strips trying to minimize the amount of meat taken off. This takes time and skill.

Removing collagen from the outside of cuts is something we teach at the CIA for cuts that are going to be sauteed. Denuding beef tenderloins for saute or carpaccio, veal leg sub primals for cutlets or scallopine, pork loins for medallions, or lamb loins for noisette, is part of the skill set a trained chef or butcher needs for creating refined meat portions. The skill also applies to fish butchery. Peeling a salmon is a common task that our students learn in the seafood class. Peeling a salmon and denuding a porkloin are cleaned very differently with the salmon laid skin side down and flat on the table while the loin is peeled skin up. So while peeling the loin I decided to see what would happen if I flipped it over and tried to clean it like a salmon. After a few gouges and mis-fires I got the hang of it. Instead of a thin section removed I got almost all of the silver off in one shot. It was not easy but it was fast! So next time your peeling a thick collagen band off a piece of meat, think like a fish butcher and flip it over, skin side down.

Large processors no longer peel either siver skin on meat or salmon skin. Today we have automated skinning machines that can do the job in seconds. The salmon skinner is super fast and requires basically no skill. Meat skinners require a little skill and the worker must where special gloves that shut off the machine if contact is made.

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

My friend and butcher Josh Applestone had the opportunity to appear on the Martha Stewart Show. The show's theme was butchery and Josh and Martha cut up a half hog. http://www.marthastewart.com/article/how-to-butcher-a-pig

It was interesting to see how casual Martha was with this process but understanding her background as a kid hanging around a butcher shop, it was no problem for her. Today we just don't find kids that grow up around the craft of cutting meat. As children grow into adulthood they simply haven't experienced meat cutting or even shopping for meat from a real butcher. Maybe some people, with parents that hunted or who grew up on a farm setting, have witnessed some butchery, but with the demise of the local butcher, meat has become a distant thing of mystery. Many don't wish to know where their meat comes from or how it is processed. They want it quick, simple and easy to cook. But another type of consumer may want to know how their meat was raised and processed. In days gone by there were numerous local butchers that selected meats from large markets or from farms. Some shops were focused on quality while others on price, depending on the clientele. The butcher could answer some questions about where the meat came from, local or not. They were still in touch with the farm to table trail. Today we find the supermarkets purchasing through large volume jobbers who buy from the processors on a huge scale. The butcher in a supermarket will only know the brand name of the product and that may give a regional clue as to where the meat was raised or how but not as specific as the old style market butchers.

Now we find some individuals wanting to know more about butchery. So where can they go? To the local butcher shop? Not too likely. There are some demonstrations of butchery available at culinary schools. The CIA which I am partial to, of course, offers a basic meat class which I teach a few times a year. Josh and Jessica Applestone are offering some classes now through their shop at Fleishers in Kingston NY http://www.fleishers.com/, there are some locations on the west coast that offer classes now such as Avendano's in SanFrancisco. http://www.avedanos.com/classes.html I attended a class in NJ hosted by the Mangalitsa farm Mosefund in Northern New Jersey. It was taught by an Austrian butcher who showed some alternative cutting techniques. http://mosefund.com/ A quick search on the internet revealed a bunch of classes all over the place, often offered by small shops or restaurants. Some focus on curing and sausage making more than butchery and others focus on game fabrication. I have viewed a lot of clips on Youtube, some good, some very poor, be selective.

Often people claim the art of butchery is lost but today I find a lot of new interest and willingness to explore new techniques. So get out there and learn, like Martha!

The Master Retires

On September 16th 2009 Hans Sebald retired from the Culinary Institute of America. Hans had taught the meat class for over twenty years. Hans, for those who never met him, is an old style butcher originally from Bavaria, Germany. He was a "master" butcher meaning he had been trained as an apprentice and moved his way up in skills, understanding the entire process of butchery, start to finish. I worked with Hans for the past eleven years and when I say he was an old "style" butcher I can also say that Hans was always on the "cutting edge" of the meat industry. He was always learning and reading about our industry and how it intersects with the foodservice world. He was never old fashioned in his thinking and lessons. His students were always presented current knowledge about new style cuts, modern processing methods, foodsafety concerns and new menu ideas. I learned from Hans. His cutting skills were always very smooth and accurate but at the school it isn't simply about cutting but about showing students how to cut, explaining the steps in a way that a person who has never cut meat before can feel comfortable attempting the task. That lesson, the one of patience and clarity, is a lesson that I use every day. Hans was above all a great teacher. He taught literally thousands of students the basics of butchery. His priority was never showmanship, instead a desire to share his skill. As a teacher, he was stern, professional and always fair, but also he had a sense of humor that was never lacking. He often had a quick witted response to situations. We were touring a pork plant in Iowa once while on our summer break. The typical worker attire was big boots and heavy coats. He wore shorts! We asked him why and he simply answered "I'm on vacation".
I'll miss working with him and I can only hope to be as devoted to my students as he was to his. They were all lucky to have such a "master" of education as an instructor!
