Yes, corn cobs are edible, but they are not typically consumed in their raw form. The kernels on the cob are the main edible part of corn, while the cob itself is considered less palatable due to its tough and fibrous texture. However, corn cobs can be used in cooking and have culinary applications. The cooked cob can also be used to make vegetable stock or broth as it imparts a subtle flavor. Additionally, some people use dried corn cobs as natural kindling or as a smoking agent for grilling and barbecuing foods.
