Grapefruit mojitos
Just when you thought this classic rum and mint cocktail couldn't get any better - grapefruit juice adds a sunshine tang
Put half the prawns, half the sweetcorn, half the cumin seeds, all the flour, 100ml water and some seasoning into a food processor. Whizz until smooth, then tip into a bowl.
Roughly chop the remaining prawns and add to the mixture with the remaining sweetcorn and cumin seeds, the coriander and spring onions. Mix well.
In a large pan or wok, heat enough oil to come 1-2cm up the side of the pan. Spoon walnut-sized blobs of the mixture into the hot oil. Squash down a little with a spoon and cook for 1-2 mins each side until golden brown and crisp (you will have to do this in batches). Drain on kitchen paper and serve warm.
