The King Oyster Mushroom is like the oyster mushroom's brother who has taken lots of steroids and now works as a bouncer.
I have to admit this is a bit of a sad speciment but he still tasted fantastic. I found a recipe for vegetarian bacon that was just king oyster mushroom sawn into planks, saturated with smoked paprika and salt and fried. Didn't have any smoked paprika so I used normal and it was tasty. But nothing like bacon.
I also tried grating them into ommelettes and sauces, which was very good too. In a subtle, grated way.
