One by one, removed oyster mushroom bundles from batter and into the dredge and coat. Into the batter again, and one more time in the dredge, Carefully place the coated mushrooms in the hot oil and fry until golden brown and crispy. Do not overcrowd the oil. Once golden remove from oil and place on a paper towel lined cooling rack. Repeat until all mushrooms are fried. Turn off stove and set oil aside to cool.
To make the waffles, combine soy milk and apple cider vinegar and set aside.
Make flax egg and set aside to thicken.
