Rupen Rao immigrated to America from India, bringing his mother’s recipes with him. After a few years he was teaching Indian cooking classes, which led to a catering business, cookbooks, and a line of sauces.
His saag—the word for spinach throughout much of the Indian subcontinent—curry sauce is perfect for simmering. Simply sauté chunks of chicken breast or vegetables in a pan for ten minutes, then add the sauce and simmer for another ten minutes. Or use it as a marinade for quick, flavorful grilled meats.
