The quiet first harvest — soft caps, ocean-blue blush, ready in days.

KB-LM-01

ヤマブシタケ · Beginner–Intermediate

Cascading white spines — a kitchen soft enough for crab cakes, quiet enough for broth.

KB-SH-01

椎茸 · Intermediate

The Japanese pantry classic — umami depth, patient fruiting, kitchen-table calm.

KB-KO-01

Thick stems, meaty bite — the sauté mushroom that holds the pan.

Oyster, Lion's Mane, and Shiitake — three quiet harvests in one gift.
