Part of the Feria de San Marcos was the Expo Agroalimentaria (the food exposition). Held on the Isla de San Marcos (Island of San Marcos) the expo was a fun way to try many of the different agricultural products of Mexico. One thing that we enjoyed was unlike a lot of fairs where the food is just on display at this fair not only were many things on display but we many were on sale which meant we got to try a lot of new things.
To list all of the fun food we tried would be exhausting but it seemed like the fair favorite was the gordita. A street food must try, to make a gordita they take a ball of masa (cornmeal), fry it, and then cut it in half and put ingredients in the middle. The most common gorditas were made of chicharron (fried pork grinds) or of cheese, or sometimes cheese and chicharron. Toppings included radishes, chopped onions, cilantro, and guacamole.
