Cucumber-Lime Paletas

Puree 1 peeled large cucumber (10 –12 ounces) with 1 cup simple syrup, 1/2 cup fresh lime juice, and 1 teaspoon finely grated peeled ginger until smooth. Strain through a fine-mesh sieve into a large measuring cup, divide among ice-pop molds, insert sticks, and freeze until solid, at least 6 hours.
