Tempeh Part 1: Soak, Cook, and Innoculate

Step 1: Buy package of unpasteurized tempeh (found at Noah’s at Bloor and Spadina) and dry soy beans

Step 2: Grind soy beans in grain mill, at a very loose setting, to remove seed husk.

Step 3: Soak split, de-husked soy beans overnight

Step 4. Boil soy beans for about 30 minutes until softened

Step 5. Puree store-bought tempeh to create starter

Step 6. Strain boiled soy beans, shake out excess water, then lay out on towel and roll up to absorb any remaining water (every tempeh making guide has stressed this, see photos)

Step 7. Punch holes in zip-lock bags to allow oxygen to enter fermenting tempeh (I used a fine-tipped chopstick)

Step 8: Drizzle about 3 tablespoons of white vinegar on dried soy beans and mix well

Step 9: Mix boiled, dried soy beans with pureed tempeh. Mix well, making sure to break apart any clumps and ensuring that most pieces of soy bean had touched fragment of tempeh – to evenly innoculate

Step 10: Partially fill bags with tempeh/soy bean mixture. Press flat.

Step 11: Place filled bags into a cooler with a string of non-LED, miniature Christmas lights to maintain a temperature of around 30 degrees. Monitor temperature and remove lights as necessary to prevent over-heating (I think the ambient temperature was around 22, and I needed only around 4 lights in the cooler to maintain temperature).


  1. I know this is an old post, but I wanted to say thank you for the tutorial. It will be easier for me to buy tempeh rather than the starter. I’m also assuming that you can use some of your homemade tempeh to innoculate another batch, right?

  2. I’m sure you could keep re-using your own tempeh as a starter… But, unless you practice sterile technique, you are going to gradually build up a population of pathogenic microbes. SO, maybe re-use a couple times, then start over with more store-bought stuff. You may also be able to split a pack of store-bought stuff in half, use half and freeze the other for later.

  3. Thanks for the reply. That’s a good idea. Hmm, not to find the gumption to do this.
