I covered my casserole with foil and chilled it overnight. The foil discolored the tomato sauce. What happened?

Acid reacts with aluminum foil, giving the food an off flavor and color. To avoid this, first cover with plastic wrap, then overwrap with the foil. Be sure to remove the plastic wrap before reheating the casserole.
