1 t vanilla
1/3 cup orange juice
1/2 cup butter
1 t cinnamon
Boil potatoes 45 minutes to 1 hour until tender to the touch. Drain and let cool briefly until you can pick up. Place in a bowl and remove skins (they should easily slip off with limited handling), then mash. Add remaining ingredients and beat until smooth.
Spoon into a lightly greased casserole. Bake in a preheated 350° oven for 45 minutes.
