Mushrooms

If you've previously cooked the mushrooms and have leftovers, it might be best to discard them immediately away or make a firm commitment to reheating them perfectly. This is due to the fact that mushrooms, like other fungi, are very vulnerable to harmful bacteria and other pathogens.

When cooked mushrooms aren't chilled right away and are kept at room temperature for too long, their protein structure can change, triggering enzymes and bacteria that can make eating reheated mushrooms from the microwave risky and generally unpleasant. Instead of overcooking, try to prepare only the number of mushrooms you need. Most of the time, reheated mushrooms of any kind, not simply those thrown in the microwave, are likely to give you an upset stomach. The mushrooms can alternatively be cooked and then immediately placed in the refrigerator to be eaten cold if desired.
