Description: Cast iron skillets are great for cooking a variety of foods, but there are certain foods that you absolutely can't go wrong with when cooking with cast iron. One of the best-known uses of a cast-iron skillet is for cooking steak. By creating the perfect sear on the stove and then popping it in the oven to maintain the steak's juiciness and moisture, a cast-iron skillet is a true winner when it comes to serving up T-bones and ribeye's.
