My SO and I were having some italian-themed chicken wings, and had some fresh-grated parmesan cheese on the side in a copper bowl. After our meal, we were cleaning up and transferring the leftovers to the fridge for storage, and the cheese on the bottom of the bowl had turned a light blue. Does anyone know why this happened? Given that it happened over only a few hours to just the cheese in contact with the bowl, I'm thinking it was some kind of reaction with the copper.

I made (delicious!) mashed sweet potatoes in a conventional stove-top pot, covered the pot with Reynolds aluminum foil, then put it in a still warm but off-position oven (simply to save stove-top and counter space for the moment while wanting it to stay at room-temperature). Retrieving the pot a few hours later, I found that the inner surface of the foil had turned a light brown. It was also moist from the condensation, but had remained clean, unoiled, unburnt. I've cooked quite a bit and never seen this. What could be causing such discoloration, and is it a worrying symptom (of, say, toxins in the foil)? [more inside]
