If you're mostly concerned about the "heat", the worst thing you can do is freeze & reheat: the heat will intensify with sitting and with each reheating. If your concern is inappropriate seasoning, as suggested above, turn it into something else where the flavors work well.Use it in place of "cream of" soup for your next casserole. Add sweet peppers, corn, black or other beans to make a Southwest-style meal. This would be great with leftover chicken.It might work to braise a beef or lamb roast. You can add sweetening as suggested by others to make a portion more like a glaze.Hope this helps. And don't be discouraged by failed experiments: All the great innovations came from someone doing something different.
