To make a basic daiquiri, simply combine one part sugar or simple syrup with three parts lime juice and six parts light rum. You may want to blend your daiquiris with ice or add a fresh fruit garnish.
If you're a health conscious cocktail connoisseur, you may want to replace some or all of the sugar (or simple syrup) in your daiquiris with real fruit. Blend strawberries, mangoes, pineapples, blueberries or peaches, fresh or frozen, with ice, lime juice, rum and sweetener to taste. Avoid using raspberries and blackberries because their seeds give your daiquiris an unpleasant, gritty texture. If your fruit is fresh and sweet, you may not need to use any sugar or syrup at all.
For a simple recipe you can use to make five or six single-cup servings of fruit daiquiris in your blender, mix 6 ounces of lemonade or limeade concentrate, 6 ounces of rum, 4 cups of fresh or frozen fruit and 2 cups of ice. If you want sweeter daiquiris, add your favorite sweetener to the mix. Make sure to blend the ingredients until the mixture is smooth. You can either serve the daiquiris immediately or save them for later. This fruit daiquiri cocktail mixture stays fresh for about a month if you seal it and keep it in your freezer.
