To velvet meat, coat its exterior with baking soda, then work up a marinade with whatever flavors you'd like to add (e.g. soy sauce, garlic, ginger), and add 1 ½ teaspoons of baking soda per pound of meat. Cover it and let it rest in the refrigerator for 30 to 60 minutes before giving it a quick rinse to remove any excess baking soda, and pat dry before cooking.
