This soup sounds weird until you taste it. Sweet potato and peanut butter? Trust me. West African cooking has been combining peanuts with vegetables for centuries, and once you try it you will understand why. The peanut butter adds this incredible richness and body, the sweet potato gives natural sweetness, and the ginger and chili bring heat. It is creamy without any cream, hearty without any meat, and deeply satisfying. I make a big pot every time the weather turns cold and eat it for lunch
