The tried and true recipe for making Amanita muscaria safe to eat I use. After detoxifying, they can be cooked as you would any other mushroom. You can use the proportion of mushrooms to liquid here as a guide for cooking smaller or larger amounts.
Aromatics (optional, try this after your first time)
A handful of crushed garlic cloves
Sliced onions
Dried bay leaves, thyme, rosemary, or your favorite herb, preferably fresh.
Instructions
Trim the muscaria and look them over for debris like leaves, etc. Cleaning is not a huge deal here as they will be boiled to the beyond, and vigorous water will remove most stubborn debris, but it’s good practice.
Put the mushrooms, salt and water into a large pasta pot (if you want to add aromatics, add them now) cover, turn the heat to high and bring the mixture to a boil. When you notice the water has started to boil, start a timer for 15 minutes, keeping the pot covered the entire time, with the heat on high. If the pot threatens to overflow while boiling, it’s ok to turn the heat down slightly, but the liquid should still be at a vigorous boil.
After fifteen minutes, remove the mushrooms from the pot, refresh them and swish in cool water, then lay on a tray with paper towels to dry, pressing down on them once or twice with more dry towels. Drying the mushrooms helps them not pop in the pan if you will cook them in fat afterwords. If you will add the mushrooms to soup, there is no need to dry them.
From here, the mushrooms can be cooked like any other mushroom, but will shine in soups, pickles, and long, slow sautes. They keep a remarkable flavor for something boiled in water for so long.
Eating
It’s good to start small as a precaution.
For your first time, I recommend starting with about 2 ounces of cooked mushrooms. If, the next day, if you haven’t noticed anything unusual in your digestion, feel free to consume more.

Notes
I think it’s best not to feed mushrooms that require detoxification to people unless the need for the detoxification process has been clearly explained to them.
