In a blender, combine ice cubes, lime juice and simple syrup.
Blend until smooth and slushy, adjusting texture with additional lime juice if desired.
Pour the frozen daiquiri mixture into the prepared glasses. Garnish with lime wedges or slices.
Notes
In lieu of lime juice and simple syrup, you can use 1 cup (8 ounces) of margarita mix or sour mix.To make simple syrup, blend ¼ cup sugar and ¼ cup water until dissolved before adding the other ingredients.Add more ice for a thicker daiquiri. If your mixture is too thick and your blender gets stuck, then add a splash of water to thin it out.
