3 oz of Light Rum
2 oz of Lime Juice
1/2 tsp of sugar
mint
Wet the rim of a cocktail glass and press down in sugar to get it on the rim. Put mint leaves and lime juice (per drink) in a cocktail shaker. Mash ('muddle') the mint with spoon. Add light rum and ice. Shake, strain, pour. If it's too tart, add sugar to the shaker.
