Nieve de Pitaya Sonorense

This is from Sonora. From the Yaqui and Mayo communities of the south of the state, from the Sierra del Bacatete and the towns around Hermosillo where the pitaya cactus, Stenocereus thurberi, fruits for six weeks between May and June and then disappears for another ten months. If you are reading this in November, close the page and come back in late spring. Mexican grandmothers cook with what the mercado is selling today, and in November the mercado is selling membrillo, not pitaya.

Pitaya is not pitahaya. Pitahaya is the dragon fruit, the cultivated pink-skinned tropical that you find year-round at the supermarket. Pitaya is the sour pitaya, the wild desert cactus fruit that grows on the organ-pipe cactus across the Sonoran desert. The flesh is magenta, almost violet, with hundreds of tiny black seeds that you leave in. The flavor is more wine than fruit, sour and floral and unlike anything else. Esto no es comida de un solo Mexico, and pitaya proves it. Try to find this dish outside of Sonora during the pitaya season and you will understand what regional cuisine actually means.

The technique is hand-churning in a wooden garrafa, the bucket-and-cylinder rig that nieve vendors have used in northern Mexico for over a century. Rock salt around the ice drops the temperature below freezing. You crank by hand for forty minutes. You scrape the cylinder every five minutes. The reward is a nieve with the density of gelato and the directness of fruit you picked yourself. The seeds stay whole because you stir, you do not blend. The seeds are the dish. Asi se hace y punto.

My mother never made nieve de pitaya. She was from Jalisco and pitaya does not grow there. I learned this from a senora named Dona Luz in Pueblo Yaqui in 2009 who cranked the garrafa on her porch every Saturday during pitaya season for three decades. She told me the same thing my mother used to say about cooking with the calendar: La fruta manda. The fruit gives the orders. You follow.
