Chitra Agrawal's Savory Tomato Curry is all-purpose curry. This sauce, ready to pour and heat from the jar, tastes of carmalized onions, and garlic and ginger. It's especially great used with chickpeas as a sauce for chana masala, but you could use it with chicken or lamb, with vegetables, or even just spooned over rice.
It’s on the mild side so you can spice each diner’s plate to their personal heat level (pro tip—a spoonful or two of Chitra's tomato achaar is especially great for adding a bit of spice). It's especially great as a base for chana masala.
