Those who want to dip their fangs into blood-red drinks will enjoy these cups of hot chocolate tinged with food coloring. A combination of bittersweet and semisweet chocolate gives each cup an indulgent flavor.
Place chocolate in a medium heat-proof bowl. Bring milk and sugar to a simmer in a medium saucepan over medium-high heat, stirring until sugar dissolves, about 7 minutes. Pour over chocolate, and let stand. When chocolate begins to melt, stir until combined. Whisk in food coloring. Serve immediately with marshmallow bones.
