I was in Delhi recently and had an interesting and new type of chaat at a restaurant called Veda. Spinach (palak leaves) (stemscut) were dipped in a very thin batter of besan, salt and chilli powder and fried crisp.
These were arranged on a serving dish and topped with sweet and sour tamarind chutney and beaten yogurt and garnished with a lot of fine sev. It was an extremely light, delicious and crunchy starter.
