Many people have never seen or eaten Purple Sweet Potatoes and Purple Yams. (Yams are the ones with rougher skin)
You can Roast them and make them into oven baked Fries with just a sprinkle of oil and pop them in a 350-375 oven for about a half hour and then just sprinkle them with fresh crushed sea salt and black pepper. Other people make this potato into desserts just like you can do with pumpkin. Sometimes they also show up as a mashed dish.
I like them them as steak fries.
I think Purple Potatoes are kind of cute.
