Mum's Crumble Topping Recipe
It's very simple - all you need to remember is
Half fat and sugar to flour.
eg. 6 oz flour, 3 oz butter, 3 oz sugar
8 oz flour, 4 oz butter, 4 oz sugar
Instead of all flour you can add some oats
eg. 6 oz flour 2 oz oats (8 oz), 4 oz butter, 4 oz sugar
The sugar could be white or brown - I like to use brown for more flavour either as sweetener to the fruit or in the crumble topping.
This is my go to crumble topping although if you look it up there are quite a few variations out there. I just like things simple to remember.
The topping can be sparse or thicker on top of the fruit - it's your preference.
