Simply, the King Oyster Mushroom (Pleurotus eryngii) is one of the most magnificent culinary mushrooms we have ever had the pleasure of working with. This amazing mushroom is native to areas surrounding the Mediterranean Sea, the Middle East and North Africa.

Organic C4 King Oyster Mushrooms Almost Ready for Harvest

The King Oyster Mushroom is the largest of the Oyster Mushroom genus Pleurotus. Typically, they have a medium to large cap with a thick meaty stem. King Oysters are usually harvested when the stems are several inches in length and the caps are just beginning to turn upwards into their characteristic trumpet shape (these mushrooms are also known as King Trumpets for this reason). Occasionally, if they are allowed to age, the flesh may darken or turn a light tan. This has no effect on the taste or quality of the mushroom.

As noted above, King Oysters can grow to very large sizes! The really large ones are sought after by vegan chefs who use them in place of scallops, which is why they are often referred to as “Vegan Scallops”.

King Oysters can be prepared in many different ways. They are often broiled, sauteed or grilled and can be added to soups. sauces, meat and seafood dishes. Because of their meaty texture and density, additional cooking time should be allowed. They are best stored in a paper bag in the refrigerator with a shelf life of around 10 days.
