A slightly more interesting alternative to the venerable Bocce Ball cocktail, this beverage balances out the sweetness of amaretto with the tang of pineapple juice. For an even more interesting take, try using spiced rum instead of light rum. Also, make sure to use fresh squeezed orange juice for a better flavor. As for the grenadine float, good luck with that. Mine sank right to bottom despite carefully pouring it over the back of a bar spoon.
1.5oz light rum
1.5oz orange juice
1.5oz pineapple juice
Garnish: orange, lemon or lime wheel
Shake rum, amaretto and juices with ice and strain into ice-filled highball glass. Float grenadine on top. Garnish with citrus.
