Well, by popular demand, here is the recipe for the cocktails that we make. Brian says that we usually serve them over ice, but this is how the recipe says to make them. I don't think that it really matters, as long as you have a glass in your hand!
1 part lime or lemon juice (I like the sweetened lime juice best)
1 part canned pineapple juice
3 parts gin
Grenadine to color pink
Mix in cocktail shaker with ice and shake.
