I can’t really claim any originality here, but I wanted to document this version, made with homemade tonic syrup as a tall drink, so here goes:
1 tbsp homemade tonic syrup (add 1 tbsp simple syrup if unsweetened) – I made my tonic syrup using this great recipe from Pinch and Swirl
Juice of half a lime
2 oz Ungava Gin
Stir ingredients together in a highball glass. Fill glass with ice and top with sparkling water or club soda.
