This syrup is concentrated stuff, use 1-2 tsp in 8 oz of milk. It's ultra-chocolatey, with a deep cocoa flavor, and not too sweet. This syrup is thick and smooth with a shine ...a chocolate syrup for adults. Use Dutch process cocoa powder if you want the finished product to have the beautifully deep color and flavor to which all good chocolate syrups should aspire.
