How to make your own tempeh starter culture at home

There are plenty of reasons to make tempeh at home. The most important would be It’s more tasty when you will it yourself. But not in every place can you buy the tempeh starter culture, or yeast. (In Indonesia it’s called Ragi). You can scroll down immediately to the YouTube video which shows detailed instructions on how to make it. However it’s also interesting to read some of the thoughts behind the steps.

Because it’s not available in every place, but very simple to make tempeh and the starter culture at home. I am going to share how to do this. To make the yeast at home, I will have to sacrifice one tempeh for it. With this we’ll grow the spores and gain more of it.

What do you need & the Ingredients

  • Tempeh
  • Rice flour
  • blender
  • strainer

Sacrifice one tempeh

Prepare one tempeh (you don’t need to use all if you intend to use part for cooking. Cut it in thin slices and spread them on a plate. Cover it with a plastic and poke some holes. This is done to increase humidity and so that the spores can breath at the same time. Now cover it with a cloth. Wait 1 day.

The yeast / starter culture after 12 hours

After 12 hours, it’s still too early but results are visible. just keep it covered.

24 hours later

The spores now cover all the tempeh and we’re total of 24 hours later. To increase the yield of the starter culture, I am making a tent from the plastic. This allows for more spore growth.

36 hours later, fluffy spores covering the tempeh

We’re a total of 36 hours later now. and it looks like the image. If you aren’t at this stage yet, just wait a bit more until it looks like this. It is now ready for the next step. Drying.

Drying the tempeh starter culture / yeast

The process of making the spores grow made it a bit wet. We would need to remove this moist.

Time to dry the tempeh and it’s spore. I just put it under the sun. If the sun is not shining, just do it in a dry warm place of the house. Under a lamp for example could work. The time differs for how long you would nee to dry it. But the condense / water drops would need to dissappear.

Blending the tempeh

When it’s dry, put it in a blender. You can cut it in small pieces to help this process. Start slow and go faster. Make sure not to overheat your blender!

Strain the powder

Strain the contents of the blender. You should have a fine powder. You can mix 1 teaspoon of this with 1 teaspoon of rice flour. The ratio is 1:1.

Test your tempeh starter

For 300 gr soy beans I uses 2 teaspoons of the tempeh starter, and 2 teaspoons of rice flour. The full recipe on how to make tempeh from scratch It works, and the result is super delicious.
