Aluminum foil Total weight: approximately 8 kg For camping, thick aluminum foil (e.g., BBQ type) is highly recommended. It's great for preventing the grill from getting dirty, foil-wrapped cooking, steaming, and preserving food. It makes cleaning the fire pit easier and can also be used to remove burnt-on food. Thick foil is less likely to tear and has the advantage of distributing heat evenly. It's considerably thicker than the cling film used at home, but it can be easily cut by hand. I think it can be used in various ways besides camping.
