Can we use a slow cooker to keep warm instead of a yogurt machine for natto fermentation?
No, if the temperature is too high, it will kill probiotics and make yogurt. The temperature of making yogurt is about 40 degrees. All-glass health pot or yogurt machine can make good yogurt, especially all-glass health pot, which can not only make yogurt, but also boil water, decoct medicine and make tea. It is more functional and practical than yogurt machine.
