What is going wrong with my crumble?

Well, that's what Delia says:

Now simply sprinkle the crumble mixture all over the apples, spreading it right up to the edges of the dish, and, using the flat of your hands, press it down quite firmly all over; the more tightly it is packed together the crisper it will be

That's the recipe I use, except with apple & blackberry, and it works pretty well. I'd say maybe the crumble comes out a little bit too tough sometimes, but it varies.

Crumble topping with oats, flour, muscavado sugar and globs of golden syrup FTW!
