Whatever you call it, it is YUMMY! No Japanese steakhouse meal is complete without it – whether drizzled on grilled chicken, fried rice, noodles, vegetables and as a dipping sauce for shrimp, crab cakes, potstickers and sushi, it’s simply scrumptious! It is especially good for dipping Gyoza (Japanese Dumplings.
