40g butter
315g blackberries
1 tb caster sugar

for the crumble
110g cold butter, cubed
200g plain flour
75g caster sugar

you will also need a 1.5litre baking dish, lightly greased

Preheat oven to 190. Cut apples into large chunks, put them in a pan and toss with the butter and a couple of tb of water over a med heat. When the apples start to soften but are still keeping their shape, stir in the blackberries and tip the fruit into the baking dish. Sprinkle with the sugar, if using.

Rub the butter into the flour with your fingertis or in a food processor. Stir in the sugar. Add a few drops of water and shake the bowl so that a few larger crumbs appear. This will give a lovely texture. Tip on top of the fruit, letting it sit loosely; don't pack it down. Bake in the oven for 30mions, till the apple is soft and the crumbs are golden and crisp.
