Today’s dish is from my book Eating for Pleasure, People & Planet, in which I write: “The streets of Paharganj in Delhi are home to some of the most delicious foods I’ve ever eaten. I love exploring on foot, tasting treats from stall to stall, like fresh lassi, fried puri, samosas and sweet jalebi. However, my favourite dish is perhaps the most frugal: dal fry, a classic lentil dal topped with freshly fried spices, chillies and vegetables.” Beetroot leaves are widely used in India, popular for their earthy flavour and nutritional value, and go perfectly in a warming bowl of dal.
