Use a tall glass.
Basic recipe
100 ml. pineapple juice (preferably fresh)
100 ml. fresh orange juice
30 ml fresh lemon juice
15 ml sugar syrup
Double measure (50 ml.) of white rum
Crushed ice
Shake very well in cocktail shaker and pour in glass with the ice.
Variations (not tried ):
Add fresh coconut juice.
Use grapefruit juice
mango juice etc.
Update: tried this drink a few times and came to the conclusion it really needs freshly squeezed fruit. I bought a fresh coconut (3 euro's) the other day and I'm sure the juice (about 200 ml. per coconut) would be great in this drink. And just as well without rum or any other alcohol.
