4 February 2019 Yellow Lentils (Tempeh)
Posted on February 4, 2019 by Durgan ... ils_/HTML/ 4 February 2019 Yellow Lentils
Yellow dehulled lentils were purchased from a bulk store. The purpose was to determine if they could be made into lentil tempeh. Lentils 500 ml were washed, and cooked at a gentle boil for about 30 minutes to make soft. They were cooled to ambient about 20C and starter was added about 1/2 teaspoon. The molds were used so I simply placed the beans in a plastic colander and placed in the top of the double boiler. I expected no positive results and promptly forgot them. After about 48 hours and in need of the double boiler and upon removing the lid found a perfect tempeh in the colander.A real case of serendipity. Then fermenting temperature was ambient about 20C. This is a perfect method to make tempeh without extra equipment and is a
high quality product.

It lasts forever if kept frozen and a long time just refrigerated.
You only use half a teaspoon or less for a batch of lentils.

Hi Durgan,

Raprima is also my favorite Tempeh starter! I always order it from the same site (, very good and reliable quality!

Very interesting, Tempeh fermentation at (non-tropic) ambient temperature! I never tried, but this would make the whole process much easier for many people. I always thought at low temperatures sporulation must be higher then normal. But you proofed the opposite!

Great work!

Experimenting with fermenting lentils. These were fermented at room temperature 20C. The lentils need be a bit soft. This batch was cooked in the pressure cooker for about 35 minutes. The starter was mixed and the lentils were placed in a colander. The air holes are necessary. The colander was placed in a large pot and set aside to ferment for about 48 hours at rom temperature. Cooking to the right softness appears to be a variable. Two methods of cooking pressure cooker or boiling water. I have equal success by gently boiling for 40 minutes or pressure cooking at about 35 minutes. The beans should have their shape and be soft enough to crush with the fingers. Meaning not too mushy.
