Trying to come up with a good rum punch for a get-together, I ended up with this recipe:
- 1.5 oz dark rum
 - 0.5 oz coconut rum
 - 0.25 oz fresh lime juice
 - 2 oz pineapple juice
 - 2 oz orange juice (no pulp)
 - 1 oz guava nectar
 - 1 tsp grenadine
 - 0.25 tsp almond syrup
 
Shake the ingredients together and serve on ice.
