Summer Pimm’s Popsicle
8 ounces sparkling lemonade
3 ounces minty simple syrup, see note
2 ounces Pimm’s no.1 liqueur
1 small seedless cucumber
1 mandarin orange
Stir the lemonade, simple syrup, and Pimm’s together in a measuring cup with a spout; let sit while you prepare the fruit (helps calm the fizz a bit if you let it settle).
Hull the strawberries and cut each one into four slices. Peel the cucumber, then slice off 12 thin slices (use rest for something else). Peel the mandarin orange and separate the segments; if you see any seeds, pop those out. Choose the 4 prettiest segments, and eat the rest (you won’t need them in the ice pops.
Divide the fruit evenly among the Popsicle moulds. Give the liquid ingredients a little stir, then slowly pour it into the moulds, leaving 1/2-inch of headroom (the fizz will expand as it freezes). Freeze for 90 minutes (or until slushy), then add Popsicle sticks, pushing and stirring the fruit around a bit to distribute while you’re at it.
Freeze for another 4 to 5 hours, or until solid.
