I am resisting Dr. bill's opening-- i am not going to digress into candy making-- but just now looking at the word caramel-- cara (heart -- in latin --or close enough) and mel (an interesting root that goes back to indo/europian--for sweet/honey/honeybees, as in d. melitis, or melody (sweet sounds) caramel's are "heart sweets"(sweethearts?)

and they are different substantualy from butterscotches-- if nothing else, once is a hard candy, the other a soft taffy like one-- no, no, no, no food! not even sweet stuff!
