Leftover Apple Pie
2 quart vanilla ice cream
For caramel sauce:
Stir sugar, water, and lemon juice in heavy medium saucepan over low heat until sugar dissolves. Increase heat; boil without stirring until syrup is deep amber color, about 7 minutes. Remove from heat. Add in cream (mixture will bubble vigorously). Return to low heat; stir until any bits of caramel dissolve. Add butter; whisk until smooth. (Can be made 1 day ahead. Cover and chill.)
For each parfait, layer three scoops of apple pie with ice cream. Top with caramel sauce.
