Yes, as the name implies, a steaming oven can steam or bake. I saw on her details page that the lowest temperature is 30 degrees, and yogurt can definitely be made. Yogurt can be made at 40 degrees /6 hours. I tried several times to make it in fasal's steam oven, and it all worked. The effect is the same as that sold outside, so the effect of yogurt machine is unknown. I also tried to use the built-in yogurt program, but it was not sour enough and sticky enough. To sum up, the utensils for making yogurt must be clean and oil-free, otherwise it is easy to breed bacteria and lead to failure.
