White Sweet Potato Soup is a conversation starter. It’s not something you’re served every day-if at all. I discovered the special flavor of this White Sweet Potato Soup when we were in South Africa. The chef generously told me the ingredients. White sweet potatoes are starchier and sweeter than their orange cousins. This is a quick and easy recipe that will leave everyone asking for more.
