Most Wasabi Oil is just relabelled Mustard Oil. This method uses True Wasabi and you can make it at home with a bit of time and care. Blows the store bought stuff out of the water.
Smoked Salmon and Cucumber Sushi Rolls
This is another favourite from the sushi bar.
Soba Noodle Sushi
Using soba noodles in a sushi roll. Tasty with the wasabi oil and soy syrup.
