I'm appealing to your sense of fair play here, devoid of gender loyalty. Mrs. Retro and I frequently cook on the wood stove or in the oven by wrapping edible parts of critters and assorted vegetables in aluminum foil. The fur usually flies (for the second time) over which side of the aluminum foil to have on the inside of the wrap--the shiny side or the dull side. One of us claims that the shiny side should be on the inside so as to allow the heat into the contents but then hold it in by reflection. The other one claims it doesn't matter at all. This topic has become standard dinner discussion every time we cook with foil. We anxiously await your answer with the anticipation of one of us eating crow.
