Corn cobs can be used to make corn stock.
Place corn cobs in a stock pot with plenty of water. You can also add a quartered onion, garlic clove, handful of parsley stems, and two celery stalks for extra flavor. Bring to a boil over high heat. Lower the heat to a gentle simmer and cook for 1 hour. Strain the stock and use immediately or allow it to cool before storing in the refrigerator or freezer.
Corn stock is great for recipes where you would use vegetable stock, such as soup, rice or risotto.
Topping options can be anything from spicy shrimp, scallops, sautéed peppers, zucchini or other cooked veggies.
