200g granulated sugar
½ cinnamon stick
¼ vanilla pod
2 cardamom pods, lightly crushed
1 tsp rose water
4 large lemons
Combine the granulated sugar, spices, and 240ml water in a small saucepan. Gently heat, stirring frequently, until sugar is completely dissolved. Transfer to a glass container and chill for at least 8h.
Peel the lemons, making sure to remove the white pith. Cut into pieces to remove seeds, and add the lemon flesh and any juices to a blender. Add 100ml water and then thoroughly blend.
Combine blended lemons, infused simple syrup, 1.5-2.5L water (depending on desired intensity), and ice to a large container. Mix well, and serve by straining mixture into serving glasses.
