Yam is an excellent root vegetable with slightly sticky and starchy flesh. When I first started cooking with yams I was most frustrated by many cookbooks simple explanation, cook like potatoes and the very few recipes available. While yam makes good chips and works well in dishes like dauphionoise yam instead of potatoes, I feel that it stands high as a vegetable on its own.
Over the last year in the U.K. the vegetables have begun to become popular in supermarkets and cooking magazines. These balls are a common snack in South Africa and you can adjust the flavours in them to your own taste.
