In this video, professional chef Frank Proto demonstrates how to sear proteins using a variety of cooking methods, including using a cast iron skillet or stainless steel saute pan. He explains that searing produces a crispy outer crust and juicy interior, and that it is an essential step in any dish. The video demonstrates how to sear meats perfectly, by oiling both sides and cooking on the skin side first before flipping and cooking the rest of the way on the flesh side. If the skin starts to stick, leave it alone and turn the heat down. Salmon skin is especially problematic, as it can stick to the pan and burn quickly.
