Another rum sour drink here.
Sheesh. I've had so many drinks of this type I don't distinguish them anymore. This one has a straw! Whoo-hoo!
1 oz lemon juice
1 tsp simple syrup
1 tsp water
2.5 oz light rum (Bacardi Superior)
Stir together in a highball glass and add ice, then rum. Stir and garnish with lemon and a straw.
