The humble and inexpensive cast iron skillet is one of most important pieces of cooking gear you can own, and Lodge’s highly-rated 10” model is back down to $13 on Amazon. If you don’t own one, you shouldn’t hesitate.
Cooking for one? The 8″ model is a few bucks less.
While you’re there, pick up some cast iron scrapers or a chainmail scrubber for cleaning, and a silicone handle cover to protect your hands.
