How to Make It
Boil water, ripe pear slices, granulated sugar, and apple cider vinegar in a medium saucepan until pears soften, 10 to 12 minutes. Remove from heat; let stand 10 minutes. Transfer to a blender; add fresh lemon juice. Blend until smooth; pour into a large glass measuring cup. Chill 30 minutes. Add 1/2 oz. gin to each of 6 ice-filled glasses. Add 2/3 cup pear mixture to each glass; top each with 1/4 cup chilled prosecco. Garnish with lemon peel strips.
