These fried spicy morsels are better than fried chicken... they're mushrooms in disguise!
Only after the oyster mushrooms have sat in the batter for 20 minutes, heat up the oil. Heat it up to 355°F to 360°F in a deep pot. Use a deep frying thermometer to watch this closely. It shouldn't go above 365°F.
Once the oil is at the right temperature, take a mushroom out of the batter and coat well in the breading.
Then go back into the other bowl of batter that hasn't had anything in it and coat well. Go back in the breading and coat well. Then add to the frying oil.
Fry mushrooms in batches and it will take 2 to 3 minutes to get to a deep golden brown. Cook time will vary depending on the size of your mushrooms.
Drain fried pieces over the pot with a slotted spoon and then place on a wire rack placed over a baking sheet. Do not use paper towels, as that could make the batter become soggy.
If you use a regular vegan mayonnaise without garlic in it, then you might also want to add 1 teaspoon of garlic powder.
