The sharpness of the lime granita is a treat when balanced with lovely sweet fruit. Tastes of tropical beaches

Makes 700ml (6–8 servings)

180ml caster sugar
A pinch of coarse sea salt
4 kaffir lime leaves, torn to release their flavour
1 stick of lemongrass, bruised
150ml soda water
350ml lime juice (1 lime usually yields 20–25ml)
1⁄2 small pineapple (about 150g), peeled and roughly diced*
100ml coconut cream, to serve

1 In a large saucepan, heat 180ml water, the caster sugar, a pinch of salt, the lime leaves and lemongrass until the sugar has dissolved and the flavours have fused together; this should take 8–10 mins on a medium heat. Discard the lime leaves and lemongrass.

2 Add the soda water and lime juice to the pan and stir gently (try not to stir all the bubbles out of the soda water). Pour into a freezer-proof container with a lid and freeze. Take out every hour and, using a fork, scrape the granita so that you end up with fluffy ice, rather than one big block. It should take about four hours to freeze.

3 To serve, put a generous portion of pineapple in a bowl, top with a scoop of granita and pour over a little coconut cream. Sprinkle with a small pinch of sea salt.

* This works well with any fresh fruit but if you find yourself near an Asian supermarket, stock up on rambutan, lychee or mangoes.
