A thick-stemmed Mediterranean oyster mushroom with firm scallop-like flesh, popular in restaurant cooking.
Where it grows
The king oyster is native to dry Mediterranean and steppe regions, where it grows in association with the roots of sea holly and other umbellifers. It is now one of the most widely cultivated gourmet mushrooms on the planet, grown on sterilised straw and sawdust blocks.
How to recognise it
Compared with the common oyster, the king has a smaller cap on a remarkably thick, white, central stem — sometimes club-shaped. The cap starts convex and flattens with age; the gills are cream and run down the stem. The flesh is exceptionally firm and white throughout.
Edibility & cautions
A choice edible with no significant look-alikes. The thick stem holds its shape under heat, giving it a strong appeal as a scallop or steak substitute.
Culinary use
Slice the stems into discs, score them, and pan-fry until caramelised; brush with soy and butter for a vegan “scallop.” Whole stems can be braised or roasted; the cap is good in stews and ragùs.
