"Nieve" (which literally means snow) is a water-based variation of ice cream. It dates to pre-Hispanic times when ice from the peaks of the volcanoes would be brought down and flavored with honey or sweet syrup. Xochimilco was the center for the production of this delicacy, and it was reserved for priests and nobles.
The main tent of the fair is lined with vendors of artesanal "nieve".
The traditional method of making "nieve" is similar to our old-fashioned ice cream makers.
Ice and salt are placed in a large, wooden bucket. The ingredients for the "nieve" are placed in a metal pot. The pot is rotated within the bucket and the ingredients stirred until they have congealed into "nieve".
The variety of flavors offered is mind-boggling.
Many of the names of the flavors are extremely fanciful. One has to wonder just what the heck are a "rabid dog", a "crazy penguin", "Pikachu" or "Viagra"!
Then there are exotic flavors, some of which sound downright disgusting!
I would be willing to try "rose petals". I love avocados and "mole", but I don't want them in my "nieve". And I definitely don't want rattlesnake. (Yes, the "nieve" is actually flavored with snake meat!") Nor do I want shrimp, octopus or oyster!
At the far end of the tent there was a stage where couples were dancing "danzón", a Cuban dance which came to Mexico by way of the Yucatán.
On a much more somber note... Santiago Tulyehualco suffered heavy damage in the 2017 earthquake. The parish church, which was built in the 17th century, is still closed.
The cracks by the entrance and in the bell tower are clearly visible.
