While it's obviously easy to make Wasabi Mayonnaise yourself, it's now carried ready-made in virtually every grocery store (at least it is here in rural Virginia). There are several brands & so far all of them have been good. Wasabi Mustard is also a favorite around here - adds a terrific kick to sandwiches.
