Step 1.

• Wash the limes well. Cut off both ends. Slice each lime into quarters.

Step 2.

• Add half of the lime pieces to the blender with 1½ cups cold water.

Step 3.

• Blend for 10–15 seconds only. Over-blending can turn the drink bitter.

Step 4.

• Strain the mixture into a bowl or pitcher to remove pulp and peel bits.

Step 5.

• Pour the strained lime juice back into the blender.

Step 6.

• Add remaining water, sweetened condensed milk, and ice.

Step 7.

• Blend again until smooth and frothy.

Step 8.

• Taste and adjust with more condensed milk if you like it sweeter.

Step 9.

• Serve right away for the best texture and flavor.

Tip from my kitchen: Short blending time keeps the lime peel from overpowering the drink.
