It's spelled "corn cob"—with just one "b" at the end. The term "cob" refers to the central core of an ear of corn, which holds the kernels in place. If you're shopping or searching for recipes, using "corn cob" will help you find the right products and information. The spelling "corn cobb" isn't standard, so sticking with "corn cob" is the best way to go when looking for fresh or frozen options at Walmart.

The "cob" in corn is the tough, inner part of the ear where the kernels grow. When you buy corn on the cob, you're getting the whole ear, including both the kernels and the cob. After the kernels are eaten or removed, the cob itself is usually discarded. Some people use leftover cobs for making broths or composting, but they're not typically eaten because of their texture.

The word "cob" comes from an old English term meaning a rounded mass or lump. In the case of corn, the cob is the cylindrical core that holds all the kernels together. Over time, "corn on the cob" became a common way to describe corn served with the kernels still attached to this central core, making it easy to grill, boil, or steam for a classic side dish.

Sweet corn contains dietary fiber, which can support healthy digestion as part of a balanced diet. Fiber helps add bulk to stool and can promote regularity. However, individual results may vary, and it's always a good idea to enjoy corn alongside other fiber-rich foods. If you have specific digestive concerns, consider consulting a healthcare professional for personalized advice.

Cooking frozen corn on the cob is simple and convenient. Here are a few popular methods:

• Boiling: Place frozen cobs in boiling water and cook for 5–7 minutes until heated through.
• Microwaving: Wrap each cob in a damp paper towel and microwave for 3–5 minutes.
• Air Frying: Preheat your air fryer and cook the cobs for about 10 minutes, turning halfway.

Always check the packaging for specific instructions, as cooking times may vary by product.
