-(very finely grated) This dish, a staple street food of the bazaars of Old Delhi, is wonderfully tart and hot. It requires two similar spice blends, one added to the browned onions and garlic, the other toward the end of the cooking time. Amchoor (powdered green mango) lends a haunting sourness. If you can't find this ingredient, substitute the juice and pulp of a small lime (the dish is also delicious without either). You may use Hungarian paprika as a substitute for Kashmiri red pepper; either will give color but no heat. These spicy chickpeas can be made up to two days ahead of time. In fact, their flavor improves if they are left, refrigerated, for at least 24 hours. DIRECTIONS: =========== Heat the oil in a wide pot over a medium flame. When hot, put in the minced onions and garlic. Stir and fry until the mixture is a rich medium brown shade. Turn heat to medium low and add the coriander, cumin, (NOT the roasted cumin), cayenne, and turmeric. Stir for a few seconds. Now put in the finely chopped tomatoes. Stir for a few seconds.
