I'm not quite sure what rancid smell you are talking about. I have been using CO for almost a year and mine has never had a rancid smell, even during the summer when it was constantly changing from solid to liquid b/c of the temp. I use nutiva also. The only way to make it a liquid is to keep it at like 75 degrees constantly. Also, you can add it to whatever you want...but FYI, make sure the apple juice is atleast warm/hot or the CO will become solid and you will probably be drinking CO chunks and apple juice. Hope this helps...

I think you may have gotten a bad batch. While it takes a very long time to go rancid, it can and does eventually (a year or more.) Coconut oil should either smell like a yummy, fresh coconut, or if it is refined, like nothing at all. Take it back to the store if possible and look somewhere else for a good supplier. Eating it should taste just like the coconut flakes in the baking section, except less sweet and much juicier. If you can eat a regular fresh coconut without gagging from dislike, you certainly shouldn't need to disguise the flavor of your coconut oil.

I had this experience recently with flax oil. Last bottle, yummy, nutty, mmmmmmm-good. This bottle -- bitter, gross, nasty. I need to hunt up my receipt (if I still have it) and take the stuff back.
