Wash 6 fresh limes thoroughly, cut each into 8 equal pieces.

In a blender, combine the lime pieces, 3 cups cold water, and 1 cup sweetened condensed milk. Blend until smooth.

Strain the blended mixture using a fine mesh strainer into a bowl or pitcher.

Prepare 2 cups of ice in glasses and pour the strained limeade over the ice.

Garnish each glass with a lime wedge or mint, serve immediately.
