Our family loves this pie and it is so easy.Microwaves are a lot more powerful than when Grace wrote 'Microwave Cooking My Way'so cook in intwervals of 8 minutes to thicken the juices and soften the apples.
Put pie crust in a glass or ceramic pan,sprinkle with 1 tablespoon of flour before adding the filling.
Stir 2 tablespoons of flour,sugar, cinnamon and lemon rind to mix. Stir cinnamon mixture into the apples to coat the fruit. Turn into the baked pie shell.
For the Topping:mix brown sugar, flour and oats,cut in the butter or margarine til it resembles coarse meal,spread evenly over the apples and sprinkle the cinnamon over the topping to give a nice even color.
Microwave on high power for 8 minutes rotating at 4 minutes(or use the turntable). The apples should be soft. If your juices aren't thick,microwave at 4 minute intervals on turntable until satisfactory.
