It's easy to make yogurt ago, even without heating until the milk and allow to cool. - 1L UHT milk 3.5% and 1% purchased Yogurt 3.5 (or yoghurt culture, there is the health food store or health food store) both possible room temperature. I have milk unde yogurt stirred in a liter measure together, then spread over the seven vials and leave tire 11 hours slightly longer than indicated in the description, and then into the refrigerator. In warm ingredients which time the manufacturer's instructions is lt. 5-6 hours. With a power consumption of 13 watts are a few hours more, probably not "energy-saving discussion topic".
For yogurt: Yogurt is pure, mild, free from additives and consistency when stirred, possibly soft or creamy, because without thickener. With a bit of fresh fruit and tinned or homemade jam, that's pure enjoyment. - And you know what "it" is.
