Kaffir Lime Simple Syrup:
1/2 cup caster sugar
1/2 cup water
8 kaffir lime leaves, bruised and crushed
3 lemons, juiced
2 shots vodka
2 shots spiced rum
Soda water or lemonade
Ice, mint leaves and kaffir lime leaves, to serve
Place caster sugar, water and kaffir lime leaves into a saucepan over medium heat.
Stir until sugar is dissolved. Lower the heat and boil until slightly thickened and syrupy.
Cool to room temperature, which allows the leaves to infuse into the syrup.
You can make this in advance.
Pour lemon juice, passionfruit pulp, vodka, rum and sugar syrup to taste into pitcher and give a little stir with a long spoon. Add ice, soda or lemonade, mint and kaffir lime leaves. Taste for sweetness and add more syrup if desired. Serve immediately.
