Black Pearl King Mushrooms
From
$42.00
Black Pearl King mushrooms are in a different category than oyster mushrooms — dense, thick-stemmed, with a deep umami flavor and a meaty texture that holds up to any cooking method. Slice the stems into rounds and sear them hard, and they develop a firm, slightly chewy bite that plant-based cooks compare to scallops or calamari. The dark caps add richness and depth. This is the mushroom for people who want something substantial on the plate.
These are grown on our farm in central Virginia and harvested the morning your order ships — farm to your door, nothing in between.
Every box ships with our house-made umami seasoning blend and a quick-start cooking guide. First time with these? The stem is the star — don't skip it.

The seared stem (the technique that makes this mushroom)
Slice the stems into 1-inch rounds — these are thick and meaty, and that's intentional. Heat butter or a high-smoke-point oil in a pan over medium-high heat until it shimmers. Place the stem rounds flat in the pan, press down lightly, and leave them alone for 4 to 5 minutes. You want a deep golden-brown crust. Flip once, cook another 3 to 4 minutes. Season in the last 30 seconds. The caps can be torn and added to the pan in the final 2 minutes — they cook faster.
Pro tip: These are excellent for plant-based "scallops." Sear in butter with a little garlic, finish with a squeeze of lemon. Serve as a starter or alongside pasta.
Why Black Pearl King Mushrooms
King Oyster and Black Pearl King mushrooms are among the most studied gourmet varieties for their exceptionally high ergothioneine content — a powerful antioxidant that accumulates in human tissue and is linked to cellular protection and longevity. Clinical research also shows oyster-family mushrooms support immune function, gut health, and natural GLP-1 hormone response.
Their thick stems provide significantly more bioavailable nutrients per serving than thinner-capped varieties — you're getting more with every bite.

Care and Handling
When your box arrives: Put the mushrooms in the refrigerator right away. Black Pearl Kings are denser than oyster varieties and hold up well — they'll stay fresh for 7 to 10 days. Cook them within the first 7 days for the best texture.
Breathable Storage is Best: Keep mushrooms in their original packaging, a paper bag, or a container with a slightly open lid. This allows air circulation and prevents moisture buildup. Avoid airtight plastic bags.
How to Clean: Wipe the caps and stems with a dry paper towel. They rarely need rinsing. If needed, a very quick rinse is fine — pat dry immediately.
Always Cook Thoroughly: Cook mushrooms to an internal temperature of 165°F (74°C). Cooking not only makes them safe but also unlocks their best flavor and texture.
