1. Crumble:
   • 100g plain flour
   • 100g butter cut into small
   • 80g soft brown sugar
   • 50g porridge oat
   Fruit:
   • 6 large ripe plums halved and stoned
   • 1 tbsp soft brown sugar

   1) To make the crumble topping. Put the flour and butter in a food processor and pulse to crumbs. Tip into a bowl and add the sugar and oats. Sprinkle the mixture with 2 tbsp cold water, then use a fork to mix everything together, creating a crumbly texture with a few large clumps. Chill until needed.
2. 2) Heat oven to 200C and tip all the fruit ingredients, except the blackberries, into a large ovenproof dish. Add 50ml water, cover with foil and bake for 1 hr. Remove the foil and remove the star anise. Add the blackberries to the dish, sprinkle over the crumble mixture and return to the oven for a further 25-30 mins until the top is golden. Serve hot or cold.
