Question:

Why is one side of foil shinny and the other side dull?

Why is one side of foil shinny and the other side dull?

Answer:

Wiki says: Aluminium foil has a shiny side and a matte sideThe shiny side is produced when the aluminium is rolled during the final passIt is nearly impossible to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollersWhen the sheets are later separated, the inside surface is dull, and the outside surface is shinyThis difference in the finish has led to the perception that favouring a side has an effect when cookingWhile many believe that the shiny side's reflective properties keep heat out when wrapped on the exterior and keep heat in when facing exterior, the actual difference is imperceptible without instrumentation [7]The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80% [4].

What a trip, I just made the same thing and here's what I did: I browned off some Ground Turkey, drained it, then added some Jalapeno and Onion Seasoning Mix, cooked off a bag of steamed veggies (carrots, green beans, corn and peppers) threw them into the pot with some leftover Salsa, (wish I had a big, fresh tomato) then heated up some white rice (wish I had Orzo) and that was dinner ! And WOW, it was fantastic!!!!!!!!! All leftovers, used stuff I had around the house, my wishes were thoughts I had for next time to make this dishAND, I have enough for leftovers that I can put in scammbled egges, put over pasta or make Turkey, Veggie Taco's, or put into a basic tomato soup, but these are my tastes, they may not be yoursAs soon as I make a dish that's pretty good (and I don't cook in small portions) I immediately think of ways to eat it for several days but in different waysHope this helps you out today or gives you an idea for your next quick dinner idea!
