How Is Tempeh Made?

A simple look at the soaking, cooking, and two-day fermentation process that transforms soybeans into tempeh.

Tempeh starts with simple soybeans, but they go on a pretty amazing journey. First, the soybeans are soaked in water to make them softer. Then their outer skins are removed and the beans are cooked a little.

Next comes the really interesting part, "fermentation". Tiny helpful living organisms are added to the soybeans. Think of them as tiny workers helping the beans change into something new. Over about two days, these tiny helpers grow and create soft white threads that connect all the soybeans together.

You can imagine it like building with blocks. At first the soybeans are separate pieces, but the tiny helpers act like little strings that tie everything together into one solid cake.

When the process is finished, the tempeh becomes firm, light-colored, and has a delicious nutty smell.

Long ago in Indonesia, people often wrapped soybeans in special leaves instead of using modern packages. Nature helped do some of the work, and families passed down these traditions from generation to generation.

So the next time you see tempeh, remember: it started as ordinary soybeans and transformed into something completely new, kind of like a food superhero origin story.
