Wasabi paste in industrial quantities. If you or your business have a tendency to go through wasabi like nobody\'s business, Yamachuu\'s wasabi powder may be just what you are looking for. Coming in a catering size 1kg bag, this wasabi powder lasts in the pantry for a long time without spoiling, and need only be mixed with water to make vibrant, fiery wasabi paste, ideal for serving with sushi or mixing with mayonnaise. It can also be added as a flavouring to soba, udon and other noodle dishes, or to add a Japanese twist to steak, seafood salad and Dim Sum.
