Tempeh is a traditional Indonesian food made from fermented soybeans. It is created by cooking and fermenting whole soybeans with a specific mold, usually Rhizopus oligosporus. This process binds the soybeans into a firm, cake-like structure, which can be sliced or crumbled for various dishes. Rich in protein, fiber, and vitamins, tempeh is a popular meat substitute for vegetarians and vegans. It has a nutty flavor and a chewy texture, making it versatile for stir-fries, salads, and sandwiches. Additionally, tempeh is considered a probiotic food, promoting gut health due to its fermentation process.
