This cornbread is moist with a pleasant taste of winter squash. Any winter squash will do, but buttenut really brings this dish to life. Butternut squash is commonly used in South Africa. It is often used in soup/stew or can be cooked on a grill and often used as a mash added to various dishes. Grilled butternut is normally either seasoned with spices such as nutmeg and cinnamon. If you have a cast iron skillet, use it instead of the loaf pan.
