| 3 medium cooking apples |
| 170g / 6oz granulated sugar |
| 170g / 6oz butter or cooking margarine |
| 280g / 10oz Self-raising flour |
OPTIONAL INGREDIENTS
3/4 teaspoon cinnamon
1/2 cup rolled oats or Corn Flakes (most crunchy breakfast cereals will do)

Turn your oven on now so that it's pre-heated ready to cook later on! Heat settings are 180°C / 350°F / Gas Mark 5, slightly lower (170°C / Gas Mark 4) in a fan oven.

When apples are peeled and especially when sliced, their attractive white flesh will very quickly turn a 'not-so-attractive' brownish colour. This makes absolutely no difference to the taste, but 'looks' are important. The method described below therefore leaves the peeling and cutting of the apples to the last minute.
There is one 'trick' described at the end to make the crumble surface look really brown and nice, but please do keep an eye on the timing. A brown crumbly topping looks absolutely delicious, but a black and burnt top is not so good.
Watch our video lower down this page showing exactly how we made this apple crumble. Also read some of the comments left by other cooks at the bottom of this page, they may well inspire you to tweak the recipe slightly and make it your own.
Recipe by David Marks.
Mix the butter / margarine with the flour in a dry bowl using a fork until you have a texture like breadcrumbs. It's not important that every single bit is like breadcrumbs, but try and get most of it like that. This will take about 3 minutes. If you are adding the optional ingredients of oatmeal or Corn Flakes, do it now. Mix it all in well.
Add 4 (not all the 6) ounces of sugar to the mixture and mix it all together with the fork. This will tend to make the mixture even more like breadcrumbs. That's your crumble mixture made and ready.
Peel the apples and cut each one into four parts. Cut out the core from each of the sections (see picture on the right).
Slice the apple quarters - no need to slice them too thinly, about six slices per quarter section of apple will do just fine.
Put the apple slices into the casserole dish. If you are adding the optional cinnamon, do it now. Make sure it is sprinkled evenly throughout the apples. Sprinkle the remaining 2 ounces of sugar evenly over the apples.
Now, evenly spread the 'crumble' mixture over the sugared apples.
Put this into the middle of your pre-heated oven at 180°C / 350°F / Gas Mark 5 for 40 minutes.
One trick you can use now is to put the apple crumble under a hot grill for about 30 seconds to 'brown' the crumble topping. Keep a good eye on it though because 30 seconds too much can result in a very black crumble topping!
If there is any apple crumble left over, cover the dish with tin foil and it will keep in the fridge for a couple of days.

Answer: I haven't tried it for 12 but I have for 6 people and it worked fine. You could make two pies for 6 each to be certain. But I see no reason for it not to work for 12. My advice would be to make the crumble topping in two batches otherwise mixing it might be difficult. Make sure your oven is well pre-heated and be prepared for cooking to take a bit longer - the guide is that when the topping is golden brown it's done. And with such a large amount read the instructions carefully before starting - especially the bit in red about adding only some of the sugar to the crumble mixture - the rest is sprinkled over the apples. Good luck and let us know how you got on.
Yes that's fine, in the USA they use mainly eating apples. Maybe a little less sugar is required because the eating apples are sweeter than cookers.
