Hello jazzguy550,
Senbei, like wagashi is one of those things people don’t really make at home in Japan. It is too much work and requires some utensils and equipment not normally found in a home kitchen.
Do you like senbei that much to go to the trouble of making it? I think that making it, and making it taste good will be a real chore. Better to just order some from Japan if you can’t get it where you live, I think.
