Chai milk granita with spiced plums

Pour 400ml cold water into a saucepan and add the cardamom, fennel, cloves, cinnamon, ginger, peppercorns and icing sugar. Stir to dissolve. Bring to the boil over a medium heat, then add the tea or teabags and simmer over a low heat for 3 minutes. Take off the heat, stir in the almond drink, then loosely cover and leave to cool and infuse for 30 minutes.

Pour the liquid through a sieve or tea strainer into a 1-litre container, discarding the solids. Freeze for 2 hours, then use a fork to scrape the frozen mixture from the edges of the container into the creamy centre. Repeat 4-5 times every 30 minutes, until the granita is completely frozen, with a sandy texture of ice crystals.

Meanwhile, make the spiced plums. Put the brown sugar and 100ml water in a saucepan and stir to dissolve. Add the spices and cook over a medium heat for 8-10 minutes until you have a light caramel. Add the plums and carefully toss in the caramel. Take off the heat, carefully pour in the vinegar and gently mix, coating the plums. Allow to cool to room temperature.

Just before serving, scrape the granita with a fork. Divide the plums among bowls (discarding the spices) and serve with the granita. Sprinkle with cinnamon (if using).
