As far as I can tell, the actual in-game recipe for NA only needs 1 Mushroom. Unless I got really lucky making 7 in a row with only 1 mushroom. Not sure if cooking level affects that, but I was Skilled8.

In EU version too, only 1 Mushroom need.

Confirmed, 1 mushroom only. Subbable (i used Ancient mushroom, 2 dried seafood subbed for 1 fresh)

1 driend octi works 100% of the time im m6 cook

[Dried fish] entry is incorrect since recipe accepts only SEAFOOD. Use [Seafood] for reference what is considered to be seafood.

Pour la version française la seule recette qui ait fonctionné après des dizaines de tentatives est :
- 1 Fruit de mer ou 2 séchés
- 1 Champignon
- 2 Assaisonnements
- 1 Fromage (Obtenu en séchant du lait)
