Prepare the limes: Wash thoroughly and quarter them. For a slightly less bitter taste, remove the white pith if desired.
Blend: In a blender, combine the quartered limes and cold water. Blend on high for 30–45 seconds until smooth.
Strain (optional): Pour the mixture through a fine mesh sieve to remove pulp and seeds.
Add the creamy element: Stir in the sweetened condensed milk until fully combined. Taste and adjust sweetness if needed.
Serve: Pour over ice cubes in tall glasses. Garnish with a lime slice or mint leaves if desired.
