Got this idea from Vosges chocolates, which I adore.
Hot cocoa packet
8-10 oz water
1/4-1/2 tsp cinnamon
1/8-1/4 tsp cayenne pepper
splash vanilla extract
(I don't measure, I just shake)
Mix it up and drink it hot or cold. It's got a nice hint of warmth in the back of your throat when you drink it. Go easy on the cayenne until you figure out how much you like!
