You will need:
– 3 oz. grape Jolly Rancher-infused vodka (see below)
– 0.25 oz. lime juice
To make the infused vodka: Unwrap 10–12 purple Jolly Ranchers and put them in a seal-able jar or bottle. Add 1½ cups of vodka, seal, shake, and let sit overnight or until candy fully dissolves when you shake the bottle. Chill until ready to use.
Add 3 oz. infused vodka and lime juice to a Collins glass with ice, stir, and fill with seltzer. Garnish with lime slice.
