Glass Bakeware Warning

Do not use glass bakeware when broiling or when a recipe calls to add liquid to a hot pan, as glass may explode. Even if it states oven-safe or heat resistant, tempered glass products can, and do, break occasionally.


  • This flank steak is best cooked over a hot charcoal fire, but it will also work on a gas grill, indoor grill pan, or broiled.
