If you go to a Japanese ramen shop and see Batta Ramen, or an izakaya and see Enoki Batta ----it simply means that butter is used in the preparation.  Like corn, crab goes will with some kind of butter.  This inspiration of enoki batta I often order in an izakaya becomes the stuffing for Alaskan king crab legs.  Simply enoki and shiitake mushrooms, butter, a little garlic, and some yuba.  All heated 'til warm and still emulsified like a beurre fondu for the crab. Simple, ono.
