4. Corn Smut
Corn smut isn’t actually even technically a food; it’s a fungal disease found in certain types of corn (like maize) that is caused by a bacterial infection. That hasn’t stopped certain cultures from eating it, however. In parts of Mexico it is even considered a delicacy.
When served with a meal, corn smut is usually roasted and added to a soup, a taco or a quesadilla. Surprisingly, corn smut actually enhances the nutritional value of the corn it infects, adding a lot more protein and soluble fiber.
