What side of aluminum foil reflects heat?

The reflective surface will reflect heat and the matte side will absorb heat. If you’re baking or defrosting, the matte side will absorb more radiant heat and reflect less infrared heat while the shiny side will reflect more of both, so it makes more sense to bake and defrost with the matte side facing up.
