Overview
King oyster (Pleurotus eryngii) grows as a single thick stem with a small cap rather than a cluster. Its dense, meaty texture makes it a favourite for scallop-style dishes and hearty cooking.
Growing conditions
Colonise supplemented hardwood sawdust at 20 to 24°C, then fruit at about 15 to 18°C with high humidity and strong fresh air. Low fresh air produces tall, thin stems, so ventilation and light are key to thick, well-formed fruits.
In the kitchen
King oyster has a firm, meaty bite and a mild, savoury taste. Sliced thick and seared, it holds its shape beautifully. Cook it fully to bring out its texture.
Grower tips
It is a little more demanding than other oysters, so it suits growers who have run a few blocks. A cool, well-ventilated fruiting space gives the best stems.
