Question: I bought Wasabi powder and soy sauce powder to make my own Wasabi/soy almonds. I found out that the Wasabi powder has no taste without water- how can the makers make Wasabi tasting almonds: I had tried before using Wasabi paste and then dehydrating them, but definitely lose the punch.
This recipe may appear a bit fussy with emptying and filling frypans or skillets with liquid, but the effort is worth it. You will want to make more of these. 🙂
