Wash the limes thoroughly under cold water to remove any dirt or residue.
Cut off the ends of each lime.
Cut the limes into quarters, then slice each quarter into smaller pieces.
Remove any seeds if necessary.
In a blender, combine the quartered limes with the granulated sugar and cold water.
Blend on high speed until the limes are thoroughly pulverized and the mixture is smooth.
Place a fine mesh strainer over a large pitcher or bowl.
Pour the blended lime mixture through the strainer, using a spoon or spatula to press down on the solids and extract as much liquid as possible.
Discard the pulp and seeds.
Stir in the sweetened condensed milk until well combined.
Adjust the sweetness according to your preference by adding more sugar if desired.
