  • Cast Iron

  • A cast iron skillet is built to last, capable of surviving the harshest environments. Its heavy construction ensures even heat distribution, making it perfect for cooking over a campfire or on a portable stove. Unlike flimsy non-stick pans, a well-seasoned cast iron skillet can handle high temperatures without warping or melting.
  • Skillets can be made from different types of material. Stainless steel, aluminum, and cast iron are common options. Some skillets are made from a combination of aluminum and stainless steel. Aluminum pans that have a thin gauge (read: not very thick) aren't the best choice since they are more likely to warp.

  • But it's not just about the taste; it's about the spectacle. Watching your meal being prepared is part of the charm. The chef's deft movements, the flicker of flames beneath the iron griddle, and the final flourish as your plate is presented – steam rising, juices mingling – all contribute to an unforgettable moment.
