I can only think of three uses for corn cobs.
- Shooing stray cats out of the yard.
- Making vegetable stock.
The cob to sweet corn has a lot of flavor. Use corn cobs, a carrot, a stalk of celery, a small onion and some thyme and bay leaf. Cover with water and simmer for three to four hours. Add more water from time to time. Strain and freeze. This makes a great vegetable stock for winter soups. If you have frozen corn you can prepare a great cream soup.
