Tempeh is a traditional Indonesian food.
It is a fermented food made by the controlled fermentation of cooked soybeans with a Rhizopus mold.
The tempeh fermentation by the Rhizopus mold binds the soybeans into a compact white cake.
People can cook tempeh in a variety of ways, but most Indonesians bake it with a little oil and salt like in this recipe.
Tempeh is a great source of protein.
