Prep notes
Birch conk, simmered. Fibre and a little iron. Not a culinary mushroom — a decoction. Identity: only on birch, the rust-char crust. Usually prepared before eating. Per 100 g figures match this catalogue row.
Caution
Grocery / shop food data only. Not a wild forage guide. Thrive shows composition curiosity — not medical advice.
