Grown for hearty meals

Black Pearl is for people who want mushrooms at the center of the plate. Thick stems, seared like a small steak. You get a filling food with protein, B vitamins, and the same good compounds gourmet mushrooms are known for. You grow it, pick it, and cook it.

A ready-to-grow block on organic hardwood, made and checked in Carthage. Cooler rooms make thicker stems. A harvest you can serve as dinner.

Why people cook Black Pearl as dinner

What it can add

These stems are dense food: more chew, more plate. People cook them when they want mushrooms to feel like a meal — protein, B vitamins, dietary antioxidants such as ergothioneine, and a simple sear.

Grow it and make it yourself

We grow this block on organic hardwood in Carthage and check it before it ships. Keep it cooler than the others. You spray, pick the stems, and sear them. You see the mushroom from bag to plate.

How to use it

Slice the thick stems. Hot pan. Sear until brown. Salt at the end. Serve as a side or as the main. Cook fully. This is food, not tea.

As food

Thick-stem gourmet fungi are protein, chew, and a plate that is not a garnish. They also carry dietary antioxidants such as ergothioneine. Cool room, open the top, sear the stems through. Food first — not a tea.

Food and traditional tea — not a medicine. These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease. If you are pregnant, nursing, or on medication, ask a clinician before making functional mushrooms a daily habit.

What you are actually growing

Black Pearl was bred for the dense stem of a king trumpet with the friendliness of an oyster. It wants 50–65°F. Warm houses make skinny stems. Cool rooms make a harvest.

Not harder than oysters — just cooler. Basement, mudroom, or spring garage.

How to fruit this block

1

Find the coolest honest room

50–65°F. Warm houses make skinny stems.

2

Open the top and scratch

Fold the bag down. Lightly scratch the surface with a clean fork.

3

Keep the surface wet

Mist several times a day. A tent with air holes helps.

4

Harvest thick stems

Twist the cluster when caps are still slightly convex.

Harvest

Stems are the prize. Keep them long. Trim substrate at the base.

After the last flush

A second flush is possible after rest and a cold soak. Then the block goes to the garden.

In the kitchen

Slice stems into coins, score, sear until deep brown. Butter, soy, lemon.

A first recipe

Black Pearl ‘scallops’

1-inch coins, scored both faces, 3–4 minutes a side. Garlic, lemon, parsley.

If something looks wrong

Skinny stems

Too warm or too little air.

Pins abort

Surface dried out. Increase misting.

No pinning after two weeks

Confirm it is under 67°F. Scratch again.
