Can household ovens keep warm?
Yes, but it's more expensive. The oven doesn't have a long shelf life. It needs to be kept warm for a while. For example, I bake bread at home and ferment the oven temperature to forty degrees.
Generally, the oven doesn't have this function, but you can look for some ovens with a fermentation function that keeps the temperature at more than 30 degrees during fermentation, but the temperature is slightly lower.
