What side of the aluminum foil should touch the food?

For regular aluminum foil, it doesn't matter which side touches the food; both shiny and dull sides are equally effective for cooking, baking, or wrapping, as the difference in appearance is just from manufacturing.

The only exception is non-stick foil, where the dull, coated side should always face the food, as noted on the packaging.
