The municipal market of Jerez is a working market rather than a tourist attraction, which is precisely what makes it worth visiting. Here you can find fresh produce from the surrounding countryside, local cheeses, dried chiles, and the ingredients of Zacatecan cooking — pozole, asado de boda, and enchiladas mineras — that you will find on restaurant tables around the plaza. The market is busiest on Saturday mornings when vendors from surrounding villages arrive.
The food stalls at the back of the market serve cheap, filling lunches. Look for birria (slow-cooked braised meat, typically goat), gorditas stuffed with bean and cheese, and atole for breakfast. This is the cheapest and most authentic eating in Jerez, and the atmosphere — cooks working over clay pots, vendors calling out the day's prices — gives a truer sense of the place than the restaurants facing the plaza.
