4-5 pounds Sweet Potatoes peeled (about 5 large)
4 tablespoons (1/2 stick) margarine
1 cup dark brown sugar
1 tablespoon vanilla extract
1/4 tsp salt
1/4 cup Whiskey or Bourbon such as Jack Daniels

Directions:
Preheat oven to 375 degrees.
Cut the Sweet Potatoes into 1/2 inch slices. 
Steam the Sweet Potatoes for 10 minutes or until soft but not mushy. 
Remove potatoes from the steamer and set aside.
In a small saucepan, melt the margarine over medium heat. 
Then add the brown sugar, vanilla and salt. 
Stir continuously until the sugar is dissolved. 
Stir in the Whiskey or Bourbon and cook for 5 -10 minutes or until slightly 
thickened, stirring occasionally.
Spray a large 9 -13 inch glass baking dish with nonstick cooking spray. 

Place the sweet potatoes in pan and drizzle the sauce on top.
Bake uncovered for 1 hour. 
Baste with the sauce every 10 minutes to keep the potatoes from drying out.
