Replace the pineapple with sweet and sour and a splash of 7up you have a purple hooter.

My recipe for the summertime:
Lemongrass mojito

Take fresh lemongrass and mint smash gently in a shaker with pestle
squeeze juice from 1/2 lime
add crushed ice
add 2oz-4oz light rum depending on size of glass
add some (i do about 1/4 of the alcohol content) simple syrup, top off with club soda
stir

Enjoy!

For a completely different taste, use a nonflavored Dark Rum

For a light light drink throughout the day you can have a

Creamsicle (just like the ones you had when you were a kid)

1 oz Amaretto
2 oz OJ (no pulp)
splash of cream

Shake over a little ice, strain, serve.
