Chef Roger Mooking believes your hands are "your most powerful tools in the kitchen", but he also advocates using only the sharpest knife. He demonstrates in a short video how to use them together.
Mooking is showing off a hand technique similar to the chef we shot for tips on dicing an onion like a prod, but, to be honest, the camera work here's a little steadier. There's also a good verbal explanation and mental reminder on what you should be doing—"cupping" the hand next to the knife, without having it feel tensed or squished.
Mooking's got a way with a chile pepper. What other knife skills have you picked up in the kitchen, professional or home? Enlighten your fellow chefs in the comments.
