Aluminum Foil

[Anonymous Modernist 847]

I have always wondered if it makes a difference what side of the foil one uses when roasting/baking/braising in an oven. I would assume that having the shinier side face down (facing the food) would reflect the heat onto the food better and create a more stable cooking environment. Thoughts?

I've always subscribed to the idea that the difference is probably very small. Though I still find myself wrapping food that will be chilled or frozen shiney side up

to add to interesting trivia. aluminum foil is shiny on one side and dull on the other because of the manufacturing techniques. In fact, it makes no difference which side is up or down.
