There are a few ways to prepare the little sweet delights. My usual way is to boil them whole and peel them when they are done. Just to make sure to peel straight after cooking otherwise it becomes harder to peel. you can also roast them in the oven.
I like them as simple snack, addition to my soups or with any grain. You can make a sweet tasting pate as well.
Even though they are called NUTS. they contain little fat and calories. the carbohydrate amount is quite high, having as much starch as potatoes.
