DEFINITELY the foilBecause the foil is so thin, the heat is released very quickly (there is more of the metal in contact with the air)The pan will still be hot because of its thicknessWhile the surface is in contact with the air (releasing heat), the core is still hot They both start at the same temp, but the foil's core is so thin that the heat dissipates so quickly that you can touch it as soon as it is on the counter.
