Monkey Wrench, and Mojito revisited

The next drink in the book is the Mojito, which if you aren't familiar with you must have been under a rock for the last couple of years. But I already covered this topic about a year ago. Let me give you Mr. Boston's recipe just for good measure.
2 tsp Sugar
4 sprigs fresh mint
1 lime, halved
2 oz light rum
club soda
Muddle sugar and mint with soda water in pint glass. Squeeze both halves of lime into the glass, leaving one hull in the mixture. Add rum, stir, and fill with ice. Top with club soda. Garnish with a mint sprig.

On to the Monkey Wrench, then.

It's a greyhound with rum. And as rum actually adds flavor, unlike vodka, this drink is probably an improvement. I squeezed fresh juice for this, which added pretty pink pulp. Also, the fresh juice is a little harsh, so I ended up adding a teeny dash of simple syrup to take the edge off. Another way to go might be salting the rim.

Recipe:
1.5 oz light rum (Bacardi Silver)
Grapefruit juice

Pour rum into n ice-filled collins glass. Fill with grapefruit juice and stir.
