1Fresh Wasabi Rootwhich equals 3-4 tablespoon of grated wasabi
1teaspoonMirin(a sweet Japanese cooking wine)
Once you have your wasabi root, grate it on a Microplane or other fine grater.
Next, add the grated wasabi to a bowl along with soy sauce, rice vinegar, and Mirin (a sweet Japanese cooking wine).
Whisk these ingredients together until they are well combined.
Then taste the sauce and adjust the seasoning as necessary.
If you want a thinner sauce, you can add a bit of water or additional soy sauce. For a sweeter sauce, add a bit more Mirin.
Once you are happy with the flavor of the sauce, transfer it to a jar or other container and store it in the fridge for up to 2 weeks.
You can usually find fresh wasabi at your local Asian market, or you can order it online. If you can't find real wasabi root, you can also use powdered wasabi and use 5-6 tablespoon instead, but the flavor will be somewhat different. Store in the fridge in an airtight container for up to 2 weeks.
