Plum cobbler

1) Preheat the oven to 190C/Gas 5
2) Spread the halved plums over the base of a 2 litre/3½ pint shallow ovenproof dish and sprinkle with 100g/4oz of caster sugar.
3) To make the cobbler sift the flour and baking powder into a food processor, add 100g/4oz of caster sugar, a pinch of salt and the butter and blitz until the mixture looks like fine breadcrumbs.
4) Beat the egg and buttermilk together and add to the dry ingredients. Mix together into a soft, sticky dough.
5) Drop dessert spoonfuls of the mixture over the top of the plums, then sprinkle with the almonds and the remaining sugar.
6) Bake in the oven for 30-35 minutes until golden and bubbling,
7) It is done when a skewer, pushed into the middle of the cobbler topping, comes away clean.
8) Leave to cool briefly before serving with some custard.
