I made some wasabi from powder and let it sit a little so the flavors can mature, then i stuffed the wasabi inside a small batch of dates and then dipped them in tempered dark chocolate. They tasted great! The only thing is that when i came back to eat another date a few days later, the wasabi tasted horrible. I know that wasabi has a shelf life of two or three days max!
My question is how do the Japanese and Asians cover nuts and crackers in wasabi? I have tasted dried green peas covered in powder wasabi that has been sitting in a package for while and it still tastes great. How can get the wasabi to last longer inside the date just the crackers and peas that we buy in Asian stores?
