Can UHT milk be used to make yogurt? So I know you can't use UHT milk to make cheese, because of the way the proteins get denatured at that temperature.  But can you use it to make yogurt?
UHT (Ultra High Temperature) processing kills all the pathogens in the milk, so it can be conserved for a long time. However to make yogurt you add bacteria (lactobacillus), so if there aren't other microorganism it should be even better.
