Hanger Steak is a lesser known but very flavorful cut of beef. It has so much flavor because it comes from the diaphragm that is needed for breathing, and has therefore had a lot of use in the life of the steer or cow. Hanger steak is called onglet in French, and longhaas or karweivlees in Dutch. It is best when served medium rare, but it can be slightly tough when prepared like a regular steak. With sous-vide we can fix this, because we can cook it for a longer time without taking it over medium rare or we can apply the technique that I have called warm aging.

It is possible to tenderize beef by boosting the activity of calpain and cathepsin enzymes in the meat through bringing the meat to temperatures of 39.5C/103F for calpains and 49.5C/121F for cathepsins. These are the same enzymes that are at work when meat is aged at refrigerator temperatures (both for dry aging and for aging in vacuum), but much faster and (compared to dry aging) without drying the meat. If you can find dry aged hanger steak there is no need to apply warm aging, but I don’t expect this to be a cut that is available dry aged. I finished cooking the steak at 55C/131F for medium rare. You could also cook it longer at 55C/131F instead of applying warm aging, but the meat would turn out less juicy and a bit more like medium. Continue reading “Hanger Steak Sous-Vide”
