You can find cast-iron cookware in a variety of shapes and sizes. The most popular cast-iron pieces are skillets and Dutch ovens, but you can find all sorts of other basic cast-iron pans and pots, too:
Skillets: Cast-iron skillets come in a variety of sizes, from very small (approximately 6 inches in diameter,) to very large (over 15 inches in diameter). With average depths between 1 1/4 inches and 2 1/2 inches (depending on the size of the pan), these pans are great for all kinds of cooking tasks.
Fry pans: Fry pans are similar to skillets except that the sides of fry pans are deeper (usually 3 inches or deeper) so that the grease doesn’t splatter as much when you’re frying.
Griddles: Griddles can be round, square, or rectangular, and they come in various sizes. They have a smooth surface and shallow sides (usually 1/2 inch or less).
Grill pans: Exactly what they sound like: Pans that you use to grill food, either on the stovetop or over a campfire. The ribbed bottom keeps the food out of the drippings and leaves nice sear marks.
Dutch ovens: Dutch ovens are deep-sided pots with lids that you can use on the stovetop or inside the oven. They’re extremely versatile. You name it; a Dutch oven can probably do it.
