6 cups cubed watermelon (from ¾ of a 6-lb. baby seedless watermelon)
¾ tsp. kosher salt
Lime wedges (for serving; optional)
Method of preparation
Purée watermelon in a blender until smooth. Strain through a fine-mesh sieve into a large pitcher or measuring glass, pressing on solids to extract as much juice as possible; discard solids. Mix in salt.
Pour juice into ice-filled glasses. Garnish with lime wedges if desired.
