* The Bartlett Pears should be pared and thinly sliced.
Combine the pears, orange juice concentrate and lemon rind in a bowl and toss lightly. Arrange the pear mixture in the unbaked pie shell. Prepare the Spicy Crumb Topping and sprinkle over the pear mixture. Bake in a preheated 400 degree F. oven for 40 minutes or until the pears are tender. Cover loosely with aluminum foil after 30 minutes if the top becomes too brown. Cool on a wire rack before serving.
SPICY CRUMB TOPPING: Combine the flour, sugar, spices and salt in a bowl. Cut in the margarine, using a pastry blender, until the mixture is crumbly.
