Peel & cut the apples and add them to a pan with the water, sugar and vanilla essence. Cook them over a medium heat till the apples soften but still hold a little bite
Grease & line a springform tin (that will fit in your camp oven) with the pre-made pastry
Add the cooled softened apples (and a little of the juice) & the frozen blackberries to the pastry lined tin
For the Crumble
Add the flour & the butter to a bowl, rub the butter into the flour using your fingertips
When the flour & butter mixture looks like breadcrumbs add in the brown sugar, oats & coconut
Top the apples & blackberries in the pastry with the crumble topping.
Lower the pie into your camp oven onto the trivet - place the lid on and put in the side of the fire on some coals. Add half a shovel of coals to the top of the camp oven too. Cook for 35 mins.
Remember to rotate the oven a ¼ turn in the fire every 5 minutes so that the pie cooks evenly in the heat of the fire
Best served with custard or if you have a 12v freezer, vanilla ice cream!
Tips
Keep the fire going with a couple of small logs to allow the heat to penetrate the side of the oven as well as the top and bottom (always rotate a ¼ turn every 5 mins for even cooking). If the top of the crumble is not browning as you like apply more coals to the top.
Fold a 45cm length of tin foil flat to about 6 cm wide and use as a lifting handle under the tin.
