1.Process corn and onion until well chopped (it should still have some texture, not a paste). Transfer to a medium bowl. Add soy sauce, coconut cream and egg. Sift flour and baking powder over mixture. Using a rubber spatula, fold together until just combined.
2.Heat oil in a wok or large heavy-based saucepan over moderate heat (oil is ready when a cube of bread crisps quickly without absorbing oil). Deep-fry heaped tablespoons of mixture, in batches, turning once, for 2-3 minutes or until golden brown. Using a slotted spoon, transfer fritters to paper towels. Keep warm.
3.CASHEW AND BASIL SALAD: Toss watercress, basil, onion and cashews in a large bowl. Whisk remaining ingredients in a medium jug. Drizzle dressing over salad; toss to coat. Serve with fritters and sweet chilli sauce.
