The King Oyster is also known as the Eryngii, King Trumpet, French Horn, Argonane, and¬†Cardoncello–just to name a few.¬† Gorgeous in appearance, the King Oyster’s firm stem and blossoming top are each edible and delicious! Delightful sliced and sauteed, stir-fried, baked, or used in soups and stews, the King Oyster has a very sublime, subtle flavor that works well with chicken and fish, in particular.
