I freeze some of my curries, if there is enough left for a portion.
But instead of just microwaving them, I defrost them in a microwave then cook/reheat them in my curry pan.
I add a little oil to the pan, add the curry, rinse out the container with a little water (don't want to waste any

) and add that to the pan also. Cook/heat it through on a med/hot heat for 2 to 3 mins, until hot and correct consistency (because of added water).
To me it is nicer than just microwaving them in the container.
