This is a beautiful drink. Slightly tart but also sweet and delicious. Once you've gone to the effort of making the syrup it is very quick and easy to make many yummy drinks. Would be good to have for a special occasion.
1/2 tsp tartaric acid
200g passionfruit pulp (fresh or from a jar)
50ml lemon juice
Sparkling water, mint leaves and ice cubes to serve
Combine the sugar, tartaric acid and 50ml of water in a small saucepan over a low heat.

Cool to room temperature then stir in the passionfruit and lemon juice.

Add 2 more tsp of syrup into the top of the glass
