Can I use aluminum foil to make a sandwich crust?

Yes, you can use aluminum foil to make a sandwich crust. While it's not a traditional method, aluminum foil can be used to hold the sandwich together, especially for sandwiches that might fall apart easily. However, it's important to note that foil doesn't contribute to the taste or texture like a proper crust would. It's also crucial to ensure the foil is food-safe and clean before use. For a more authentic sandwich crust, using bread is the best option, but if you're in a pinch or for a temporary solution, aluminum foil can work.
