Step 1

Wash limes thoroughly with dish soap and cold water. Slightly trim either end of the lime (which is usually mostly pith), and cut each lime into eighths.

Step 2

In a high speed blender, working in two batches at a time, blend half of the limes, half of the coconut water, and half of the granulated sugar.

Step 3

Strain through a fine mesh strainer into a large bowl or pitcher, and repeat with the second half of the ingredients.

Step 4

Whisk in sweetened condensed milk along with salt.

Step 5

Serve immediately over ice and garnish with more lime wedges if desired. This is best consumed within the first hour.
