4 limes
4 cups cold water
1 12-oz can sweetened condensed milk
Wash the limes and peel two of them. Combine the lime and water in a blender. Blend for about 10 seconds.
Strain the juice through a fine-mesh strainer, pressing on the pulp to extract all the juice.
Return the liquid to the blender and the sweetened condensed milk. Blend until creamy and frothy.
Add some ice and blend again until cold. You can add more water to taste if it is too strong for you.
