Tempeh is a traditional soy product originating from Indonesia. It is made by a natural culturing and controlled fermentation process that binds soybeans into a cake form. Tempeh is unique among major traditional soy foods in that it is the only one that did not originate from Greater Chinese cuisine. It originated in today's Indonesia, and is especially popular on the island of Java, where it is a staple source of protein. Like tofu, tempeh is made from soybeans, but it is a whole soybean product with different nutritional characteristics and textural qualities. Tempeh's fermentation process and its retention of the whole bean give it a higher content of protein, dietary fiber, and vitamins. It has a firm texture and an earthy flavor which becomes more pronounced as it ages. Because of its nutritional value, tempeh is used worldwide in vegetarian cuisine, where it is used as a meat analogue.
