Pour 3 cups of cold, filtered water into your blender. Add 1 cup of sugar, adjusting according to your sweetness preference, and blend on high for 30 seconds until the sugar dissolves completely.

Incorporate 3 tablespoons of sweetened condensed milk and blend for an additional 20 seconds until smooth and creamy.

Wash and cut 2 fresh limes into small wedges.

Add the lime wedges to the blender and blend on medium speed for approximately 20 seconds to break down the lime pieces.

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

Taste your lemonade and adjust sweetness with more sweetened condensed milk if necessary, blending briefly to mix.

Serve the strained lemonade in glasses filled with ice and garnish with lime or shredded coconut.
