Dairy-free apple crumble pie. A sweet, cinnamon flavoured apple pie with crumbly streusel topping!
Rub the margarine into the flour to form breadcrumbs. Stir in the icing sugar.
Add the water and stir until the mixture starts to stick together. Use your hands to gently press it into a ball of dough. It will look crumbly at first but will come together. Wrap the dough in plastic wrap and chill it for 30 minutes in the fridge.
Preheat oven to 200°C/400°F (or 180°C/350°F if you're using a fan or convection oven).
Once removed from the fridge, gently press the dough in your hands to get rid of cracks or crumbly bits. Be careful not to overdo this or you may end up with tough pastry.
On a floured surface, roll out the dough until it's just larger than a 9-inch pie or tart tin. Do not stretch the dough to fit your tin or it will shrink while baking.
Cover the pastry with baking paper then add baking beans (or uncooked rice) on top.
Bake for 15 minutes, remove the paper and the rice/beans then return to the oven for a further 15 minutes.
Turn the oven down to 180°C/350°F (160°C/325°F for fan or convection ovens) for the next stage.
Peel, core and slice the apples to around ¼ of an inch thick. Squeeze the lemon juice over them to prevent browning, then place to one side.
Add the water, cornflour, sugar, lemon zest and cinnamon to a large pan. Mix well before placing over medium-high heat. (Make sure to mix in the cornflour while the mixture is still cold to prevent lumps forming.)
Add the apples to the pan and gently simmer for around 10 minutes. Stir often until the mixture becomes slightly syrupy and the apples have softened. Remove from the heat and set aside to cool.
Mix together the flour, brown sugar and cinnamon in a bowl. Rub in the margarine to form large breadcrumbs.
Pour the filling into the pre-baked pastry case. Spoon over the crumble topping, covering the apple mixture and pat it down into place using the back of a spoon.
Bake for 45 minutes.
Leave it in the tin to cool completely before attempting to cut into slices. Once sliced, you can warm it back up in the oven or microwave to serve.
