standard kitchen aluminum foil has two sides per sheet one is shiney the other is dull bake on?
Actually, both sides are the sameThe only difference is that when the aluminum is rolled up, the part that touches the rolling mechanism becomes shinyIt doesn't make a difference what side you use, as aluminum will cook well on either sideIf however, you want it to reflect well, you should use the shiny side towards what you want it to reflect.
