** Purple sweet potatoes from Odisha trending

The sweet-scented spuds from Sanjog Sahu’s Mati Farms are a summer surprise at chefs’ tables and will soon find a prominent place in restaurant menus

Chindi Varadarajulu, chef and owner of Chennai-based Pumpkin Tales, is delighted with the purple sweet potatoes she has sourced this summer. They have brought back memories of her childhood in Singapore, she says. The potatoes, a deep purple with a sweet fragrance when cooked, are from Mati Farms, a farming enterprise in Odisha — the state leading in sweet potato production across India. “I have been actively looking for them for the past year. They are versatile and lend vibrancy to the simplest recipes,” says Varadarajulu.
