Ingredients:
4 - large sweet potatoes
1/3 cup - butter
8 cups - water
1/2 cup - tomato sauce
2 tbsp - half and half
2 tsp - salt
1/8 tsp - freshly ground black pepper
1 pinch - dried thyme
1 cup - cashew halves

Method:

1. Preheat oven to 375 degrees F (190 degrees C).
   
2. Bake sweet potatoes until soft, about 45 minutes.
   
3. Remove potatoes, and set aside until cool enough to handle.
   
4. Then peel, and place in a large bowl.
   
5. With a large fork or potato masher, mash potatoes for 15 to 20 seconds (they do not need to be mashed smooth).
   
6. Spoon the potatoes into a large saucepan over medium-high heat.
   
7. Stir in butter, water, tomato sauce, and half-and-half. Season with salt, pepper, and thyme.
   
8. Stir in cashews, and mix well.
   
9. Bring to a boil, reduce heat to medium low, and simmer until cashews are soft, about 50 to 60 minutes
