Indian Yogurt Dishes?

Something like a korma or quorma (however you wanna spell it, you know what I'm talking about) any yogurt heavy gravy dish.

Are these ok to freeze? More than likely, chicken would be the meat in the dish.
I'm thinking about making some bigger quantities of some of these gravy dishes that I like, and freezing in smaller servings. I have no experience with freezing yogurty things that would be heated afterwards. Anyone?

Will usually seperate due to the water content freezing and the fat content in the yogurt not freezing.-Dick

I freeze my batches sans yogurt, and swirl it in upon re-heating. It does 'break' when frozen, as Dick says, but I haven't noticed too much of an adverse taste effect.
