Hibiscus pepper lime

Brilliant red, the tartness of hibiscus flowers is balanced with sugar and just a prick of pepper. Combine 10g (¼ oz) dried hibiscus, ½ teaspoon black peppercorns and 100g (3½ oz) sugar in a pan with 500ml (2 cups) water. Cover, heat slowly to melt the sugar, then simmer for 10 minutes. Leave to cool, add the juice of a lime, then strain. Serve chilled.
