Hmm. I think I would go with one of the low(er) fat versions of regular milk first.

Funny--I hadn't thought of cocoanut milk having fat--but cocoanuts certainly do!

Some recipes on the web call for chicken stock, also (of course, that can certainly have fat in it.)

I think over all 1% milk might be the way to go for a lower calorie version. Maybe I'll try a smaller version tomorrow with that and curry as corbaegirl suggests above.
