If you are preparing quick breads or cooking something else where you need that delicious crisp edge, then a cast-iron pan is the right thing for you. There are quite a few desserts where cast-iron pans are perfect. Nevertheless, your skillet won’t do if you intend to cook savory foods. The problem is that residual flavors may transfer to other ingredients which will give your cakes or muffins a savory flavor. The best decision is to have a few skillets and use each for a different type of food.
