My batch of homemade tempeh is spoiled, who can I prevent this in future?
There could be many reasons but the most important one is the incubation of moist beans. Moist is the number 1 reason which will spoil your batch of Tempeh. Then other organisms will grow and compete with the tempeh mould. This will result in a slimy texture and a strong smell of ammonia. Other reasons could be: – using old or inactive starter(starter should be kept in a dark, cold and dry place) – working conditions where not hygienisch – too high incubation temperature which kills the mold (temperature should be 80 – 86F).
