If the chonkier mushrooms are your thing, this bundle is for you. Get one of each of our beefiest oyster mushrooms - the king oyster and the black pearl oyster.


Both varieties sport large, meaty caps and thicker stems than other oyster species, perfect if you're interested in experimenting with them as a meat alternative in a recipe. 

Black Pearl Oyster Mushrooms are a genetic hybrid of King Oyster and Pearl Oyster mushrooms. It is a rare and beautiful variety of oyster mushroom that is characterised by their dark brown to black caps and pearl-white stems. They have a mild, earthy flavour and a slightly chewy texture.


King oyster (Pleurotus eryngii) is native to the Mediterranean regions of Europe, the Middle East, and North Africa. These mushrooms are particularly popular in Chinese cuisine, adding a unique and savoury dimension to various dishes. With their meaty texture and earthy flavours they are a fantastic mushroom to cook on the grill. When cut into rounds and smothered in butter & garlic, their large stems make a great vegan alternative to scallops.
