There are a lot of people out there who call cooking an “art,” but what is it, really? In reality, cooking, especially baking, is pure chemistry: a science. Here, America’s Test Kitchen shows us how to properly slice steak to maximize tenderness, no matter what the cut. Did you know that if you slice flank stank and a strip loin against the grain, they are actually comparable in tenderness? (Many people assume flank steak is always tougher.) This video proves it’s all about the way you cut your meat, not necessarily the way you cook it. Show your dad how it’s done the next time he posits that he can cook a better steak than Bobby Flay with his “secret trick.” Now you’ve got a trick of your own up your sleeve.
