Many Curries freeze very well. I use the basic recipe on the jar of curry paste I get at a local Indian store (English company it turns out). Basically it is just brown onions, add in cut up meat (I use chicken), Brown then add curry paste cook 1 minute more and then add tomato and water. From there I diverge from the recipe and throw a couple of pans full into a crock pot and leave a few hours then let cool and once cool enough freeze in sandwitch bags. I'm doing the cook for one thing. I then put bags in larger freezer bags. That part is very nice. Unlike many dishes that usually are frozen in a dish, which limits how many of them you can do.
When it comes time to serve just reheat and also cook some rice. It is pretty much a real meal.
