Yam is an excellent root vegetable with slightly sticky and starchy flesh. When I first started cooking with yams I was most frustrated by the lack of recipes available and guidance to simply cook like potatoes. While yam makes good chips and work well in dishes like dauphionoise. I feel that it stands high as a vegetable on its own.
With the diversity of people around the world yams have begun to gain in popularity, they're more widely available and feature in many recipes. These balls are a common snack in South Africa and you can adjust the flavours in them to your own taste.
