My stepdad brought Indian home cooking into my life. He and my mother had been high school sweethearts, American students at an international school in the foothills of the Himalayas where my stepdad had grown up, stuffing himself on dal and pappadums throughout childhood and cultivating a lifelong craving for fragrant vegetarian curries. Thanks to him and to recipes like this mixed bean masala, it’s a craving I now share. Quick, healthy and economical, it’s an easy recipe to double and freeze in preparation for chilly winter nights, when the scent of onion, ginger and spices bubbling on the stove will warm up the whole house.
