Pima farmer Jose Angel Galaviz Carrillo's wife Esthela makes tortillas by hand, cooking them on top of the wood stove, which also serves as a heat source during chilly Sierra Madre mountain winters a their home in Maycoba, Sonora, Mexico. (From the book What I Eat: Around the World in 80 Diets.) Her two youngest sons wait for breakfast, while her oldest son helps José with the milking. Practically self-sufficient, the family does buy some basic food and supplies, like powdered milk, at Disconsa, one of a network of government-subsidized stores catering to rural communities, in the town of Maycoba, six miles from their home. They grow their own corn and grind it, but Esthela keeps bags of masa flour on her pantry shelf for making tortillas. MODEL RELEASED.
