• 1 1/2 pounds sliced seedless watermelon , rind removed
• Zest of 1 lemon
• 3/4 cup fresh lemon juice
• 1/2 cup mild honey (such as orange blossom)
• 1 lemon , thinly sliced, for garnish

In the bowl of a food processor, place watermelon and process until very smooth. Strain through a coarse sieve set over a bowl, stirring to push through any pulp. Pour juice into a large pitcher. Add lemon zest.

In a bowl, whisk lemon juice and honey until honey dissolves; stir into watermelon juice. Stir in 1 1/2 cups cold water; cover and refrigerate until very cold. Serve over ice and garnish with lemon slices.
