SERVES 4 Vietnamese Lemongrass, Clam Tomato Soup

THIS CLASSIC SOUP is simple and aromatic with lemongrass and fresh dill. The Vietnamese like to add fruit to savoury dishes, so pineapple or fresh star fruit can be added as an option. Season the soup to your personal taste with fish sauce, sugar, tamarind and chilies, but it should be a balance of spicy, salty, sweet and sour.
