Rum and Coke
Rum and Cokes are one of the world’s great mixed drinks. If you like yours with spiced rum try keeping the rum in the freezer, it helps to crystallize the sugar and produces a much more interesting drink than room temperature rum.
Also, don’t call the Rum and Coke a Cuba Libré, that’s a whole other drink. Curious, read Why the Cuba Libré Hates Being Called a Rum and Coke.
