Finding commercial supplier prices for starter spores to be outrageous, it was decided try and make my own from a previous batch of Tempeh. Procedure was to allow a block to ferment longer and form dark areas which are the desired spores. This block was then cut into small pieces and dehydrated at 36C until very dry. Then the dried pieces were made as fine as possible in a blender and coffee grinder. The resultant powder was then mixed with rice flour as a storage substrate. The amount of rice flour added was twice the weight of the dehydrated spores. Store in a sealed container in the refrigerator for few days or the freezer for long term. The material must be completely dry to prevent mold. The dehydrating temperature should not exceed 36C to avoid destroying the spores. Instead of rice flour for a storage substrate soy flour might be used. Application is three teaspoons of Tempeh Starter to 500 ml of dried soy beans.
This is tempeh made from the home starter produced. It is a perfect run. This means tempeh may be made without using expensive commercial starter. This batch was fermented 36 hours. I am a happy traveler.
