Make your own fermented legumes

Legumes are a cheap source of plant-based protein and other nutrients, including B vitamins, iron, and calcium. But they are difficult to digest, cause intestinal discomfort and contain anti-nutrients. Fermentation removes these disadvantages. TopCultures produces and sells tempeh starter and other starters to make fermented legumes.

Tempeh is a traditional soy food originating from Indonesia. It is made with a fermentation process that binds soybeans into a cake, sort of like a veggie burger patty. The fermentation of soybeans really brings out their nutritional value. It has an earthy flavor and firm texture as well. It’s extremely tasty, and it’s used as a meat analogue around the world. If you are a vegetarian or vegan, consider this food. Natto is a traditional Japanese food that is made by fermenting soybeans with Bacillus natto. It contains some very healthy ingredients, such as vitamin K2 and nattokinase.

What do you need?

To make tempeh you need whole soybeans, a tempeh starter and a bit of vinegar. Although tempeh is traditionally made with soybeans, you can also make it from other legumes, such as black beans, lupins and peanuts. Natto is made from soybeans and a natto starter. No other ingredients are required.
