The Culprit: I was making some scones recently that called for heavy cream. I reached into my fridge and grabbed my carton and poured into my measuring cup. It was lumpy and disgusting and had gone bad. I mean, I know that I have been trying to cook a little bit healthier lately but come on really. I have never had cream go bad. I always use it up before it is anywhere near that point. I was seriously appalled with myself.
