How to cook the perfect steak for every temperature — according to the executive chef of a world renowned steakhouse

Just a few short blocks from the New York Stock Exchange, another Wall Street institution sits at its centuries-long perch at the triangular intersection of William and Beaver streets.

Delmonico's is widely considered to be one of the very first sit down restaurants in America, born at a time when New York offered little more than taverns and oyster cellars. Culinary mainstays like eggs benedict and baked Alaska were invented in their kitchen.

Executive Chef Billy Oliva invited Business Insider into the Delmonico's kitchen to give a master class on cooking steaks to temperature.
