Be aware of what you cook tomatoes with. The high acid content of the tomato slows down the cooking process of some other foods. Dried beans cooked with tomatoes added to the pot can take up to 20 percent more cooking time than beans without tomatoes added.

Don't pile your tomatoes in a container that doesn't breathe. I like my baskets or grass mesh plates, and I layer them single deep, stem end down to prevent bruises and premature rotting.

Never use an aluminum pot, pan, or utensil when cooking tomatoes - or any other soft metal items for that matter. The acidity in the tomato doesn't do well with them; they create a chemical reaction that can turn cooked tomatoes bitter and fade the color, and the food will absorb some of the aluminum!
