Mexican Hot Chocolate ~ Chocolate Caliente
In a small saucepan over medium heat, bring the milk to a boil. Add the chocolate (the quantity depends on how rich you like your hot chocolate), reduce the heat, and stir until the chocolate has melted. Remove from the heat and froth vigorously with a molinillo, a whisk, or a hand mixer until you have a nice, bubbly foam. Immediately pour into a mug.
