Classic Brazilian Limeade

1.Cut the washed limes into quarters, removing any thick white pith or tough stems if desired, though leaving the peel on is essential for the authentic flavor.

2.Place the lime quarters into a blender with the 4 cups of cold water.

3.Pulse the blender 5 to 6 times using short bursts; do not over-blend, as this will make the drink bitter from the lime peels.

4.Strain the mixture through a fine-mesh sieve into a pitcher, pressing down on the solids to extract all the liquid, then discard the pulp.

5.Return the strained lime liquid to the blender, add the sweetened condensed milk, sugar, and ice cubes.

6.Blend on high speed until the mixture is smooth, creamy, and frothy.

7.Pour immediately into glasses filled with extra ice and serve chilled.
