Cutting King Oyster Mushroom
For this recipe, we will cut the king oyster mushrooms in to chunks. f they are on the larger size, you can cut them vertically first (length wise) and then cut them in to ½ to 1 inch width. Or you can do this very cool cutting style called 'roll cutting'.
Roll cutting aka oblique cutting is a technique where you can cut long veggies like zucchini, carrots, Chinese eggplants, in a way that will expose the most amount of surface are - this makes it cook faster and absorbent of sauces/spices.
