Just because Charmander is going through an awkward teenage phase doesn't mean he's lost his edge. In addition to the natural heat and spiciness of our ginger beer, we'll be adding in even more ginger to bump up the spiciness even further.
After you get your hands on some fresh ginger, cut off a piece about the size of a quarter, and peel it. Somewhat counter-intuitively, it's easiest to peel ginger with a regular spoon instead of a normal peeler, so don't waste time rifling through your kitchen drawer. Once the ginger is peeled, grate the whole thing into the rum and ginger beer before flaming the orange. The oils from the orange will affect the ginger as well, deepening its flavor.
Pour 1.5oz rum into a chilled glass and cover with ginger beer, then peel a piece of ginger about the size of a quarter and grate it into the drink. Flame an orange peel and squeeze the oils into the glass.
