Making a really good cup of cocoa is simple if you follow a few easy steps. First, melt a good quality chocolate. If the chocolate seems grainy once melted, the cocoa will seem grainy too. Next, pour whole milk into the melted chocolate. The fat in the milk is needed to keep the chocolate even throughout the cocoa. Skim milk allows the chocolate to sink to the bottom and should be avoided. Finally, heat the drink to the perfect temperature. Milk easily scalds and will leave an unsightly film on top of the cocoa, but no one wants cold cocoa. Now, enjoy a perfect cup of cocoa.
