Set up your workstation with 2 plates and add 1 cup of flour onto one of the plates. Stir the apple cider vinegar into the almond milk and let it sit for a couple of minutes.
Add 1/2 cup flour to another plate, season with salt, and pour in the almond milk. Whisk to dissolve the flour. Then, add a generous pinch of salt to the other plate followed by some pepper, oregano, onion powder, garlic powder, smoked paprika, cumin, and cinnamon. Mix to combine.
Coat the oyster mushrooms in the dry flour mix, then in the wet batter mix, and again in the dry flour mix. Repeat until all of the oyster mushrooms are coated.
Make the dipping sauce by making this chickpea chipotle mayo recipe or mixing mayo with a hot sauce such as sriracha.
Pour the avocado oil into a frying pan and heat up on medium heat for 2-3min. Take a small piece of mushroom coated in batter and dry flour and drop in the oil to test to see if it is ready. When there is a prominent bubbling upon dropping the mushroom in oil and it cooks to golden brown within a few minutes, it is ready.
Place in the oyster mushrooms. Fry in small batches to prevent overcrowding the pan. Cook for 2-3 minutes. Flip the mushrooms over and cook for another couple of minutes. Or cook until golden brown.
Carefully transfer the fried mushrooms onto a cooling rack or plate covered in paper towels and let them rest for a minute or so before serving.
Serve with a sprinkle of flaky Maldon salt, chopped parsley, and some lemon wedges. Enjoy these vegan southern fried mushrooms!
