Santiago Cocktail

Such a pretty drink, this  'Santiago Cocktail'  from page 154 of The Bartender's Guide. It was also a pretty good drink. I'd have another.

To mix one drink:

1/2 teaspoon Powdered Sugar
1/4 teaspoon Grenadine
Juice of 1 Lime
1 1/2 oz Rum (Bacardi Amber)

Shake with ice and strain into cocktail glass. Garnish with an orange.

Ole!
