The acidity in yogurt acts as a tenderizer, making it a perfect ingredient in marinades for grilled foods. For chicken or lamb, season with salt and pepper, coat evenly in the marinade, and place in a nonreactive container. Cover and refrigerate at least 8 hours or overnight. For fish, do not marinate more than 30 minutes.
What to buy: Use plain, natural, organic whole-milk yogurt like Stonyfield Farm. It’s tangier and less thick than other brands.
