...Usually, just as I am getting close to leaving Mexico, I find some absolutely irresistible treat and have to eat it every single day until I leave.I arrive back in the U.S. a few pounds heavier, wondering how I ever got so carried away. I return to my more or less normal eating habits and more or less normal weight, only to return and discover some new treat across the border.This week, it was apple empanadas.

Many times, I have walked right by a business with no way to recognize it after it was closed.On my first day, I found no sign of empanadas. On the second day, I asked a couple of gringos nearby, and they knew nothing about them. On the third day, I went into the flower shop and asked in Spanish. The owner pointed to the bakery.“No, not the bakery.” I told him it was empanadas, specifically, I was looking for.The people in San Miguel are used to being asked stupid questions. They answer the same stupid questions over and over, and then gringos come up with new ones.The owner of the flower shop stopped working on the roses at his ...
