The Tortilla Factory by Gary Paulsen is a picture book with beautiful illustrations that walks the readers through the process of making a tortilla from preparing the land and sowing the corn seeds to making corn tortillas in bulk at a Tortilla Factory. This was a late addition to our family book tour of Mexico. I put this on hold at our library a couple of weeks ago but it took a while for it to become available. It finally became available on the day before we left on our trip to Mexico. I brought it on the trip and read it to the boys a couple of times already on this trip.
