There are some foods that just can't handle the heat, chaos, and long hours of a food festival. Two prime examples: croquettes and spinach. Croquettes are rarely freshly fried. Once the croquettes reach room temp, they are essentially balls of grease. Yuck. Avoid at all costs. In addition, spinach turns into brown muck quickly (like, in minutes) with bitter and sulfuric flavors. Just don't go there.
