Southerners know all the secrets of tender, juicy chicken. Soaking chicken overnight in yogurt or buttermilk with live culture does a great job of tenderizing. Another method is soaking the meat in a baking soda solution to raise the pH level on the meat's surface so it can't go tough on you. Rub approximately 1 teaspoon of baking soda per pound of chicken breast, let it sit for 15 minutes (longer won't hurt it), then rinse it off, pat dry, and get cooking.
