Fermenting Beans - DIY Tempeh


  • 1 kg white beans
  • Tempeh yeast (Starter), according to the packaging


  • If your beans are still with their skins, soak them in cold water for 12 H or overnight, adding more water if needed throughout the time.
  • Once your beans are soaked for 12 H, drain and rinse them. Squeeze beans between fingers, the skins would peel easily. Separate skins from beans and rinse again
  • Drain and rinse and place them into a pot
  • Fill the pot with enough water and bring to boil
  • Once boiling, lower heat to medium and let simmer for 30 minutes
  • Once your beans are boiled, drain and place them on a long sheet and air dry them (I use electric fan btw!)
  • Then sprinkle the yeast, stir beans so yeast would cover all beans and pack them into ziplock bags
  • Punch holes all over so yeast can breath
  • Line your baking pan with clean towel (I use my instructables aprons haha), place packed beans and wrap it with the towel
  • Once wrapped, place baking pan in oven with light on and ferment beans for at least 22 H
  • After 22 H, when it's a success, you will have beans cake, firm with white spores all over.
