Barbados Punch

I made these last night and think the ratio of ingredients was really good.

for 3 servings:

3 oz. spiced rum
1 oz. triple sec
3 oz. fresh lime juice
6 oz. pineapple juice
1/4 cup sugar

add all to blender with crushed ice. blend until smooth.

the tricky part is the ice. just start with a cup or so and add more till at the consistency you like.
