The Mushroom Made For Your Grill
The stems are thick, dense and meaty. You can slice them into half-inch rounds and throw them directly on a hot grill. They'll char. They'll caramelize. They'll hold their shape.
They taste like steak dipped in umami.
This is the mushroom that makes vegetarians smug and meat-eaters curious. It's substantial. Satisfying. The kind of texture that actually fills you up.
What You'll Harvest:
- First flush: 10-14 oz (10-14 days)
- Second flush: 6-10 oz (flip the bag, repeat)
- Third flush: 4-6 oz (possible with good care)
- Total: 20-30 oz over 4-6 weeks
Flavor & Texture: Deep, earthy, umami bomb. Not mild like Blue Oyster. Not delicate like Pink. This is rich, savory, almost meaty. The stems stay firm under high heat. Slice thick and grill. Sear hard in cast iron. Roast at 450°F. It won't disappoint you.
Growing Conditions:
- Temperature: 60-70°F
- Timeline: 10-14 days to first harvest
- Difficulty: Beginner-friendly (just slightly slower than Blue Oyster)
100% guaranteed to fruit or we replace it free.
