I can't believe I finally like sweet potatoes!! Come to find out, there is a huge difference in flavor when it comes to "sweet potatoes" and "yams". I've been missing out all these years because evidently, I've never actually had sweet potatoes before yesterday! You MUST use sweet potatoes for this. They are usually smaller and one or both ends will be very pointy. The rounded end ones that look like russets are yams. Sweet potatoes are naturally sweet and soooo much better! Hope you enjoy my recipe!
