Ruby Tuesday Apple Pie

1 (9−inch) frozen deep−dish apple pie (double crust or
old−fashioned)
1 stick Butter
1 Cup Light Brown Sugar
3 1/2 tsp. Cinnamon
1/4 tsp. Allspice
1/4 tsp. Ground Clove
1 1/2 tsp. Lemon Juice
3/4 Cup flour
1/2 Cup sugar
10 Tbsp. frozen butter
1 1/3 Cups chopped walnuts
Ice cream (optional)

Let pie thaw at room temperature for 30 to 45 minutes.
Preheat oven to 350 degrees.
In a small saucepan, melt the stick of butter over medium heat.
Add 1/2 cup brown sugar, 1 1/2 teaspoons cinnamon, allspice, cloves and lemon juice.
Stir until well blended and sugar is melted, about 3 minutes.
Make an X in the center of the top crust of the pie and fold back the crust.
Pour the butter mixture evenly into the pie and then replace the crust.
Leave 4 vent holes, sealing the rest of the pastry.
Bake for 30 minutes.
Remove from the oven and set aside.
Reduce heat to 325 degrees.
Grate frozen butter into a medium−sized bowl.
Toss the grated butter with flour, remaining sugars, remaining cinnamon and walnuts.
Carefully wrap an aluminum foil band around the edge of the pie, creating a lip to hold topping.
Sprinkle topping evenly over pie.
Bake for 30 to 40 minutes. Let rest for 10 minutes then serve with ice cream, if desired.
