So far I've only used it to bread things, but I love it. I think you can use it in any recipe that calls for LC bake mix, or Atkins bake mix. I don't know about substatuting it strait for flour though.

I did move mine to the freezer. We had some whole wheat flour that was really old and got buggy. The bugs spread to my gluten. So now anything that may get buggy I keep in the freezer or in air tight storage containers.
