Start by washing four fresh limes under cool water and cut each lime into approximately eight pieces.

In a powerful blender, combine the lime pieces, two cups of cold water, and one cup of sweetened condensed milk. Blend on high for about 2-3 minutes until smooth.

Pour the limeade mixture through a fine mesh strainer into a large bowl or pitcher, using a spatula to press the liquid through and remove any pulp and seeds.

Fill a tall glass generously with ice and pour the strained Brazilian limeade over it. Serve immediately.
