Real saag! exclaimed my friend Allia, smiling as I put the dish on the table. Most restaurants say saag paneer, but what they mean is palak. Spinach. Saag is always mustard greens.

Allia would know. Not only is her family from India, but they are avid cooks. Her aunt alone, I am informed, is responsible for untold gustatory delights. She is the sort of person who converts food haters into food enthusiasts, the sort who teaches classes on the delicate art of Indian cuisine — and sets her own price for her time.
