Astoria

• 2 ounces white rum
• 2 ounces triple sec (or cointreau or grand marnier)
• 12 ounce mandarin liqueur (the brand I have is Mandarine Napoleon but I guess you can do it with Grand Marnier)
• 2 ounces grapefruit juice

1. In a shaker, put all the ingredients with ice.
2. Shake and pour in a glass.
3. Garnish with an orange slice.
4. You may add more grapefruit juice if you find it too strong.
5. That's what I did.

white rum, triple, mandarin, grapefruit juice
