Wash your limes and peel two of them. Cut them into 8 wedges. and remove the white pith.

Combine the lime wedges and water in your blender's jar and pulse for a few seconds (10 seconds maximum).

Strain the juice through a fine-mesh strainer, pressing on the pulp to extract all the juice.

Return the liquid to the blender and he sweet condensed milk. Blend until creamy and frothy. Then, add the ice and blend again until super nice and cold! :) (Too intense? Add more water or ice and blend some more!)

Serve immediately!
