Cooking is not a good or trustworthy way to make poisonous mushrooms safe to eat. Believing that cooking can remove toxins is a very dangerous mindset and can lead to life-threatening consequences.
Many of the most dangerous mushroom toxins are heat-stable. These heat-stable toxins can survive boiling, frying, baking, drying, and even pressure cooking. In some cases, cooking actually reduces toxin warning signs (like bitterness) and this makes the possibility of poisoning even more likely.
