While I do not get to play around in the kitchen as much as I would like, I was fortunate that my friend Nat invited me to help cook dinner on Saturday for a group of our friends. He is always up for experimenting so this gave us the chance to try an idea I have had in mind for a few weeks: sous vide chicken fried steak.
Chicken fried steak, in its classic rendition, is a usually inexpensive cut of steak pounded to tenderize it, coated and fried like a piece of chicken and served with gravy. During season thirteen of Top Chef, chef Jeremy Ford tried the technique of cooking a nice cut of steak in the sous vide, “gluing” chicken skin to the steak using transglutaminase and then frying the end result so the chicken skin was crispy. I was interested in trying this technique.
We followed a similar preparation, cooking a very nice grass-fed filet mignon in the sous vide until rare and then slicing it into medallions. The benefit of sous vide is that by cooking the food in a vacuum-sealed bag immersed in a water bath, the entire piece of food reaches exactly the desired temperature and then cooks no further. Instead of the outside of the steak being cooked and the inside being raw, as might happen when you fry or roast a steak, the entire cut was a consistent 131 degrees Fahrenheit and still a pretty pink.
As the meat cooked, about two-and-a-half hours, we skinned whole chickens, basically turning them inside out. This was an interesting experience, something I have never done before. The end result are these sheets of chicken skin (seen layered in plastic wrap, above) with little “fingers” of skin like a glove where the legs were.
After the meat was finished and sliced, we sprinkled it liberally with the transglutaminase. (From the molecularrecipes.com website, “Transglutaminase is an enzyme that stimulates a bonding process at the cellular level with the amino acids lysine and glutamine in proteins. It’s not technically glue, though that’s what it’s often referred to as. It’s a protein that’s present naturally in both plant and animal systems. The product used in kitchens is created from natural enzymes using a fermentation process.”)
I then wrapped the chicken skin around the steak. Trying to get the chicken skin cut to the right size was a bit tricky, and some extra transglutaminase was needed where there was overlap of the skin.
Normally, it takes about two hours of refrigeration for the “glue” to firm up. But a quick trip back in the sous vide for about ten minutes sped up the process, resulting in this tightly-wrapped packages that looked a bit like duck breasts.
When it was nearing time to serve, we dredged the pieces in a mixture of flour, salt, pepper and chili powder and fried them in about two centimeters of rice bran oil. The end result was a crispy skin and a steak that was a perfect medium rare. We served this with an onion gravy and salad.
All in all, the result was positive. We could experiment with more consistent portion control – sizes of steaks varied a bit – and maybe a liquid batter instead of a flour batter. But, overall, I would rate this a culinary success.
