Trumpet Royale organic mushrooms (Pleurotus eryngii), also known as King Trumpet or King Oyster mushrooms, in a 1-pound package. These USDA certified organic mushrooms are cultivated in the United States by Mycopia Mushrooms and certified organic by QAI.
Trumpet Royale mushrooms have a wonderful savory flavor, a firm and meaty texture, and an exceptionally long shelf life compared to other specialty mushrooms. Both the cap and stem are equally delicious, so nothing is wasted. The stem can be sliced into medallions and prepared like seared scallops. These mushrooms are incredibly versatile and can be sauteed, grilled, braised, stewed, roasted, or broiled. Their savory richness is emphasized by high-heat cooking methods.
Store in the refrigerator and use within 3 to 5 days of purchase. Washing is not necessary and may change the texture. Simply trim the bottoms and they are ready to use.
