Chicken with Onion, Bell Pepper, and Mace

Versions of this curry dot many a north Indian restaurant menu, with bell pepper and onion acting as the key ingredients and the tomato-based sauce speckled with a variety of spice blends. My version enhances the simple vegetable flavors with only a few spices. The blackened chiles provide a sharpness that is offset by sweet mace, a surprise ingredient in this easy-to-make dish for a weekday evening.
