actualy there is a difference weather it is shinny side in or out, but it is not enough of a differance for us to worry about.
3 types of heat transfer conduction, convection, and radiation, the shinny vs non shinny side of the foil will only affect the radiation method of heat transfer. but not by mush as itis shinny but not as shinny as we thing. talk a look at the oilwell firefighting suits., very shinny and very very reflective. aluminum foil is shinny but not very reflective due to the nature of aluminum. so don't worry about it. what ever way your potatoes get wraped up is ok. as for lasagnia tent the aluminum don't seal it so the moisture can escape during the whole cooking time.
