Mushrooms are ideal in a vegetable stir-fry, in homemade scrambled eggs or as a topping on pizzas. Mushrooms with colored fuzz, with weeping and rotten spots or with an unpleasant smell should be disposed of, says Lower Saxony State Office for Consumer Protection and Food Safety.
If the mushrooms are no longer fresh, leave them alone, says the consumer advice center on the lebensmittel-forum.de platform, as an infestation with mold that is harmful to health can be the cause.
