3 large sweet potatoes
1/3 cup butter
1/3 sugar
2 eggs, lightly beaten
2/3 half and half
1-1/2 oz Jack Daniels
1 tsp vanilla
1 tsp salt
2 premade 9" pie crusts
Peel and cube sweet potatoes. Place them in a large saucepan and cover with salted water. Bring to a simmer and cook until soft, about 5 minutes. Drain, mash and set aside to cool.
Preheat the oven to 350.
In a large bowl, cream together the butter and sugar. Add the eggs, half and half, Jack Daniel's, vanilla, and salt. Mix well. Add the sweet potatoes and mix until well blended.
Pour into the pie shells and bake for about 45 minutes or until a knife inserted in the middle comes out clean. Allow to cool. Serve at room temperature with whipped cream if desired.
