I came from Indonesia, "tempeh country". For me tempeh is my food, I ate since maybe I could eat solid food. Very common, people never thought how to make tempeh. You always can buy anytime and cheap. When I moved to America, I didn't find tempeh like I always ate and fresh..with the smell so nostalgic. My husband found in library THE BOOK OF TEMPEH (same author)and I learned how to make tempeh from that book. I did...then now, I confident enough to say, my tempeh is really good. Because all my friends in here says...my tempeh different and taste better. Thanks Bill !!!!!
So, we have plan...in our retire live in Mainland (maybe countryside PA) we will make tempeh company. I bought this book and my husband said, very clear the explanation about machine, room, etc.
Recommended if you want to make your tempeh store.
