My friend Roberto Santibañez, chef owner of Fonda restaurants in New York City, suggested this combination when I asked him about a chicken pie with Mexican flair. Chicken and vegetables are cooked in a tomato and chile salsa from the Yucatan called chiltomate, then topped with a cornmeal and cheese dough before baking. Though the habanero is a classic for this, serrano or jalapeño could be substituted. Sour cream harmonizes well served alongside.
