I’ve found that this is a real treat for little ones when you use semi-sweet chocolate; grown-ups usually prefer bittersweet.
3 cups whole milk
3 ounces bittersweet or semi-sweet chocolate, finely chopped or grated
Heat the milk in a saucepan over medium-high heat until it is just ready to boil. Put the chocolate in a blender and pour in the hot milk. Allow the mixture to sit for 10-15 seconds, so the chocolate begins to melt; cover securely, place a folded towel over the lid, and blend until completely mixed and frothy, about 30 seconds. Serve with marshmallows.
Makes 3 servings.
