Seijo Ishii's "Five Kinds of Marinated Mushrooms and Olives" is full of plump mushrooms! Bunashimeji mushrooms, eringi mushrooms, maitake mushrooms, mushrooms, shiitake mushrooms and olives
I actually purchased and tried the "Marinated Five Kinds of Mushrooms and Olives," a side dish sold at Seijo Ishii. This marinade is made with eringi mushrooms, buna shimeji mushrooms, maitake mushrooms, mushrooms, and shiitake mushrooms.
