This easy spiced rum cocktail quickly turned into my absolute favorite make at home adult beverage. A dark and stormy consists of ice, 2 ounces spiced rum, the juice from one fresh lime, and a crisp 8 ounce bottle of ginger beer. It's really that easy! The lime and ginger beer make a very pleasant bubbly cocktail with a bite of rum. And even though I'm no bartender, this drink comes out perfectly every time. Even when you don't measure your spiced rum and end up having a heavy pour.
