To Temper
Roast the chana dal & grind (using a little water) along with the rest of the ingredients to a paste. Temper with roasted mustard seeds, curry leaves and asafoetida.
Variation
In the above, reduce tamarind and add raw tomato (lightly steamed) to get raw tomato chutney. You could also substitute raw mango for tamarind. Another variation would be with sautéed onions.
Serves 2 – 3
