Toovar dal—also called arhar dal, toor dal, or pigeon peas, these cream-coloured split lentils, which are paler in colour, flatter, and larger than yellow split peas, are widely used for cooking in Northern and Southwestern India. They have a delightful, slightly sweet flavour and are easy to digest, especially in the famous South Indian soup-like dishes rasam and sambar. Toovar dal is available at Indian grocers.
