Thick cut for crispy chew

King Trumpet can be enjoyed in many different ways by varying its thickness. With a thick cut you can enjoy a crispy chew, but we recommend slow cooking as the best option. Simmering will not make the mushroom soggy. The mushrooms can increase the volume of the dish. Cut the caps into 4 pieces.
