While it's technically possible to cook pancakes on aluminum foil, it's not recommended. Aluminum foil can stick to the pancakes, making them difficult to flip and remove without breaking. It also conducts heat unevenly, leading to uneven cooking. Instead, use a non-stick pan or a griddle for the best results. If you must use foil, consider greasing it heavily and using a thin layer to minimize sticking and ensure even heat distribution.
