I made this a few days ago, making up the recipe using the things I know about apple crumble.

Granny Smith Apples (3-4 apples)
A large quantity of Saigon Cinnamon
A large quantity of rough brown sugar
7-8 digestive biscuits

7 -8 digestive biscuits

Fist, peel and dice the apples, and put them in a large bowl. Then, put about a tablespoon of cinnamon in the bowl and toss it, like a salad. Then, smell the apples. It should have enough cinnamon when you can actually smell it. Also taste it to make sure. Then, add brown sugar, according to taste. Then, pour the apple into a baking pan (I use an oval baking pan) Then crush the digestives (using whatever methods you can), and season them the same way. Then pour the biscuit onto the apple and sprinkle brown sugar all over it. Make sure you can not see the apples. Then, put little knobs of butter onto the crumble and put it in the oven at 180 degrees celcius for about thirty minutes.
