• 500g Soy beans already split in half and dehulled
• 3g starter on 6g rice flour
• 5ml rice vinegar

• 24h soaking of the beans at 34°C in the oven
• 12hours on keep warm function in the oven. Temperatures between 30° and 40°C
• 12hours more closely monitored in the oven to keep temperature under 40°C and closer to 30°C

Learnings: Vinegar seems to depend on the acid percentage, some ventilation would be good, to get humidity out, especially in enclosed incubators(?!)

• 500g Soy beans / partly dehulled by rubbing between hands and then rinsing with water several times to remove hulls
• 3g starter on 6g rice flour
• 8,25ml rice vinegar (4,3% acid) probably use less on higher concentrated vinegars (original FHB recipe says 5ml)

• 12hours on keep warm function in the oven. Temperatures between 30° and 40°C
• 12hours more closely monitored in the oven to keep temperature under 40°C and closer to 30°C
