Skillets: A skillet is simply a low sided, long handled pan often called a frying pan, Generally skillets come in four sizes, extra large (12 Inches), large (10 Inches), medium (8 inches), and small(6 inches). Cookbooks often refer you to certain size skillets, so it is important to know the measurement of each one. Occasionally you will have a recipe that requires you to place a skillet in the oven, so it is important to purchase skillets with handles that can withstand the heat of baking. You can also purchase skillets with removable handles.

Dutch oven or Kettle: A Dutch oven or kettle is a large heavy stock pot with a tight fitting lid. Unlike a sauce pan, these pots don’t have a long handle; rather they have two tight fitting handles along the rim on opposite sides. Dutch ovens are perfect for soups, stews, and braising meats. Kettles are good when you have a large stew or pot of soup to make or if you enjoy home canning.
