My post on Coyoacán was rather short, as I was exhausted at the time. I forgot to mention one of the really interesting dishes I had that day: Chiles en nogada (stuffed poblano chiles with walnut sauce). It's slightly sweet and very yummy. There is a recipe on the web site of Zarela Restaurant in NYC, so you can see all of the ingredients. We had it at Las Lupitas, a restaurant in Coyoacán on a beautiful square (Plaza Santa Caterina). One the plaza is a small church, Iglesia de Santa Caterina, with glass in its triple-arched facade, so that one can see all the way into the church from outside.
