Prepare apples by peeling, coring and thinly slicing.
In a bowl mix half a teaspoon of cinnamon to the apples with 3 tablespoons of flour. When apples are covered evenly add them to a frozen 9″pie shell.
In a bowl using your hands knead 114 grams of sugar, 114 grams of flour and 114 grams or margarine into a soft dough.
Break off parts of the dough into smaller pieces, flattening each section and place them on top of apple mixture (It is not necessary to cover the entire apple mixture).
Insert several wooden skewers (around 3/4 inches tall) inside the pie which will ensure the cooking bag does not touch the top of pie whilst baking.
Preheat your oven to gas mark 6 or 200 degrees Celsius. Place pie in oven bag (we recommend using a Large Bakewell oven bag) and close the bag using the tie provided. Cut the corner of the bag carefully using a scissors to let steam escape.
Place bag on roasting tray and place in the middle of the oven, making sure the bag doesn’t touch the oven walls or heating element. Bake pie for 1 hour 15 minutes or until the top of the pie is a golden brown colour.
Remove from oven and carefully cut bag open. Remove the pie and place on wire rack to cool
We recommend serving with whipped cream or vanilla ice cream.
