Today we are going to take a closer look at Tempeh Starter.

Product Highlights

Tempeh is a traditional Indonesian food made by fermenting soybeans with a starter culture. Traditional tempeh is a soybean cake that has a rich smoky flavor and aroma, and a firm nutty texture. It is a great source of protein and vitamin B-12.

Tempeh is fermented at 88°F (31ºC) which is the normal outdoor temperature in Indonesia. This traditional food often replaces meat in dishes and can be sliced, marinated, and seasoned as desired.

Product Q&A

Q. How many grams of starter per package please?

A. This starter has not been measured in grams, but it contains one US tablespoon of starter. This is enough to make 4 batches of Tempeh.

Q. Is this product made with organic NON-GMO ingredients?

A. The tempeh starter is not certified organic, but is made with non-GMO ingredients

Q. Will tempeh made with this starter sporulate (i.e. will it form black spores if incubated long enough)? Reason I ask, I see Belgium is the source and there is a well-known Belgian distributor who sells a mutant strain that doesn’t sporulate. This is supposedly a benefit, but harvesting spores is my preferred method of propagating the tempeh culture (rather than backslopping which is what kerry is referring to).

A. According to our information, the tempeh strain we sell will sporulate, but not generally within the 36- to 48-hour normal incubation period. A 3 to 4 day incubation may produce the black sporulation you are looking for.​
