The only cooking I do with yogurt is tandoori chicken. The meat is
marinated in the yogurt. It works like magic to tenderize the flesh.
When I went to a cooking demonstration the chef did a pumpkin and
butternut squash soup that uses cream. The cream is added at the end and
he stressed that you should only add the cream to what you are going to
use right away because it will separate if you re-heat it.
