- Place cucumbers and lime slices into jar. Top with gin, lime juice, sugar, and salt. Screw lid on tightly and shake to combine. Open jar and add tonic water; the cucumbers should be fully submerged.
- Refrigerate overnight and up to 2 days to allow cucumbers to pickle. (Pickles will keep in the fridge up to 1 month.)
