1 Soak the gelatine in cold water.
2 Bring 750 ml water to the boil, make tea, and infuse for about 7 minutes. Strain the tea, add the lemon juice and sweeten with sugar. Add the gelatine and stir to dissolve. Cool and leave to set slightly.
3 Transfer to small bowls with a few tea leaves, if desired, and put in the fridge to set.
4 To serve, dip the bowls briefly in hot water and turn out on to dessert plates.
