Begin by placing 6 cups of cold water into your blender, followed by 5 lime wedges and 1/2 cup of granulated sugar. Blend on high for about 30 seconds until smooth and frothy.

Once blended, strain the mixture through a fine mesh strainer into a large bowl to remove lime pulp and skin.

Return the smooth lime juice to the blender and add 1/4 cup of sweetened condensed milk. Blend until frothy and creamy.

Fill tall glasses with ice cubes and pour the creamy lemonade over the ice. Garnish with fresh lime slices.
