1 (6 oz.) limeade
6 oz. water
7-9 oz. white rum (make it strong)
1/3 to 1/2 c. sugar (or to taste)
16 oz. lemon-lime carbonated beverage (7-Up)

In blender, place limeade, rum, water, and sugar. Blend well and then stir in lemon-lime beverage. Place in freezer. Mixture will not freeze completely, but will be more like a slush. To serve: Remove from freezer, place in glasses and add garnish such as lime, mint leaf, etc.

Note: To make strawberry daiquiri, add frozen strawberries and place in blender with other ingredients.
