Watermelon Lemon Juice

Squeeze lemons into a large pitcher; add squeezed lemon quarters. Add mint and agave; mash with a wooden spoon until mint is bruised.

In a blender, puree watermelon in batches until smooth; pour through a fine‐mesh sieve into pitcher (if watermelon contained seeds) 

Stir to combine. Serve over ice if desired.  Refrigerate, covered, up to 3 days. Makes about 8 cups.
