Tempeh is a fermented soybean product that originated in Indonesia. It is made by soaking soybeans, cooking them, and then fermenting them with a Rhizopus mold. Tempeh has a firm texture and a nutty flavor. It is a good source of protein, fiber, and vitamins.
When buying tempeh, there are a few things to keep in mind. First, check the expiration date. Tempeh is a perishable product, so it is important to buy it fresh. Second, look for tempeh that is firm and has no signs of mold. Third, choose tempeh that is packaged in a vacuum-sealed package. This will help to keep the tempeh fresh.
