But they're poisonous! You say. And that's true, you absolutely should not eat raw amanitas. But you know what other mushrooms you shouldn't eat raw? All of them! Chitin is indigestible!
"Well, sure, but a raw porcini won't kill me!" That's true, but you know what will? A Morel! (If you're small). At the very least they'll make you as sick as an amanita. And you know what people do with Morels? They eat them! They're a prize edible!
"Okay, but people eat morrells but they don't eat Amanitas" okay. Well, take off your fucking anglocentrism glasses because they've been eating amanitas in India and Japan since before your country even existed.
So listen up, slice and boil your amanitas in gallons of water, and I mean gallons. Strain and rinse. Boil, strain and rinse again. Guess what you've got? A soft, buttery, delicious mushroom. Pour some garlic butter on it, or do it authentic and put it into miso soup as a nice earthy addition.
It's an edible. Change my mind.
So basically they're edible like how fugu is edible in that you need to prepare them in a very specific way without making a mistake otherwise you're dead.
They won't kill you unless you're pretty small and you don't cook them at all and it's hard to mess up boiling something. If you boiled them in too little water or didn't rinse them or something you'd probably just robo trip a little.
