A mojito without rum is not a mojito. Smash mint stalks (that's where most of the mint juices are) with equal amounts of granulated and dark cane sugar. Then stick in 1 squeezed lime, crushed ice, then Havana Club rum and soda over the top. Give a quick stir, then top with mint leaves. Fucking amazing.
And then drink it in the sun in Havana. Brings back a few memories.
