Methods

1. Place the milk, and any spices, if using, in a small saucepan over medium heat. When hot, whisk in hot cocoa mix, and bring to a gentle simmer. Continue to simmer, whisking occasionally to prevent the milk from scalding on the bottom of the pan, until the mix is dissolved, 1 to 3 minutes. (If you want a frothy cup, off the heat, use a milk frother to whip the hot chocolate before serving.)
2. To serve, remove any whole spices, pour into a mug, and garnish with marshmallows or a dollop of lightly sweetened whipped cream.
