My mom fixed these when I was a child. I really loved them. Unfortunately with 7 brothers and sisters you were lucky if you got more than a taste at a time. Of course mom would use bacon grease to fry them in. I opt for canola oil.
•4 large sweet potatoes or yams
•Canola oil for frying
Wash and peel the sweet potatoes. Slice the potatoes in thin slices. Fry in the hot oil until browned on both sides. Remove to paper toweling to drain and sprinkle top with sugar.
I have noticed lately that quite a few restaurants are serving french fried sweet potatoes. That is another option. Just slice as for fries and use a deep fat fryer.
