India is a wide-ranging country where cooking varies from region to region, so Diana decides to focus on the foods of Southern India. To celebrate South India, Jacob Leung prepares red onion bhaji with yoghurt dipping sauce, his favourite street food snack. Sarah Todd joins Diana to share her recipe for Kerala-style crispy prawns, a dish she fell in love with while opening a restaurant in India. Diana creates a fragrant vegetarian dish tadka dal, a lentil-based dal topped with tempered herbs and spices.
