Homemade Recipe for Sushi: Wasabi Roll (Hosomaki, Thin Seaweed Out Roll, 6pc)

Updated: Sep 30


If you think of “hot” when you hear the word wasabi, my guess is you probably haven’t had a chance to experience the fresh wasabi. Fresh ground wasabi is rather sweet. Sure, it does have the slight and mild “hotness” initially, but it only lasts for a brief moment, leaving long lasting mild sweet aftertaste and aroma.


Wasabi's "hotness" comes from the oxidization of sinigrin, glucosinolate substance found in broccoli, mustard, and horseradish. When the wasabi is grounder, sinigrin makes contact with oxygen. Most of the hotness lasts ten to twenty minutes. It is said the finer you grind, the better it is. The traditional grinder is made of shark skin - said to produce a hot but mild sweet taste when wasabi is grounded.


But, wasabi roll does not use ground wasabi normally put on nigiri, or used for sashimi. Instead, wasabi is thinly cut – matchstick, or Julienne– and rolled into Nori/Seaweed out, cut into 6 pcs. The result is much different taste characteristics than ground wasabi. Matchstick wasabi is not hot at all because oxidization occurs only on the outside cut surface of wasabi.


In Japan, a Wasabi roll is generally served at the end of the sushi meal, regarded as one of the finishing pieces.

TIPS

Use Fresh Wasabi

In the US, there are some wasabi farms in Oregon and California. Half Moon Bay Wasabi Company is one of them, who can ship fresh wasabi.


Storing Wasabi

Soak fresh wasabi in water and store in the refrigerator for several weeks. Alternatively, you can freeze wasabi. To use frozen wasabi, never thaw frozen wasabi. Grind frozen on the grinder. Once finished, put back into the freeze immediately. Should last for a month or two.
