(This is especially pretty as a summer cooler. Roselle are the fruits of a hibiscus and full of vitamins. They give this tea its main flavor profile. Roses add fragrance, and the hawthorn slices increase the tanginess of this thirst quencher. Make up a large jug and chill well.)

50g roselle fruits

20 dried wild rose buds

4-6 dried hawthorn slices

2 tablespoons wulong-tea leaves

Rock sugar to taste

Place all the ingredients into a large tea pot and pour boiling water over. Leave to infuse for 10 minutes, stir well, strain into a jug and chill.
