Story Behind this Recipe
This recipe was created with cut sweet potato sticks, since that was the shape used in my family recipe. This eliminates the need to deep fry. The stick shape makes for easy cooking and eating, so this is one of my stand-by recipes.
The trick to this recipe is to cook the sweet potato sticks evenly, without overcooking them. When the sweet potato sticks become soft, remove the lid and fry in oil. The outer surface will become crispy. Sweeten by adjusting the amount of sugar.
