How to make 1 cup of Hot Chocolate:
Heat 1 cup of milk (whole, 2 percent low-fat, or 1 percent low-fat) in a small saucepan over medium heat until it starts to steam and bubbles appear around the edges of the saucepan. Add 1/4 cup of hot chocolate mix and continue to heat, whisking constantly until simmering, two to three minutes longer.
Pour hot chocolate into a mug and serve, but only after making sure that the temperature will not destroy your taste buds (it's happened to me quite a bit!).
