I’ve been making a lot of apple crumble/crisps this year and I keep on forgetting my ratios, which then sends me on an Internet research hunt and then I make things up all over again. So I’m writing some things down!
My current preferred approach to the crumble topping :
Mix it all together with your hands, pinching the small pieces of butter with your fingertips. Pour on top of your fruit mix and evenly spread it out.
