Nothing is more comforting and yummy to me in the winter than hot chocolate. It reminds me of coming in after sledding all day and snuggling around the fire on our first floor, watching Christmas cartoons with with my little Auntie who lived with us, and sitting in ski lodges (all 6 times I skied!). ;)
There is a big difference between cAcAo and cOcOa. Plain and simple, cacao is the raw form of the cacao bean, whereas, cocoa is the cheap, more processed variety—which has been roasted, alkalized, molded into heated cakes, the cacao butter/oil pressed out, then powdered.
You can get cacao at any health food store, or find some great online sites where you can buy it raw, organic and in bulk.
