A cobbler is a fruit dessert topped with something rather like, but not exactly, scone dough. You can make this with any fruit - I made one a few weeks ago with nectarines and peaches, and did one on Saturday with brambles and cooking apple.
Use as much fruit as will fit in the bowl, is my rule of thumb, and I prefer to sweeten with honey rather than sugar. The topping's the thing, here.
6oz plain flour
pinch of salt
2 tsp baking powder
1 tbsp caster sugar
3 oz marg
5 fl oz sour cream or yoghurt - works fine with either
Blitz everything but the sour cream/yoghurt in a blender if you have one, or rub it to a breadcrumb consistency if you don't.
Stir in the cream/yoghurt. Turn it out onto a floured surface, and knead a bit - it'll be quite sticky, and so will you when you've finished. No need to use a rolling pin - just pat it out to about 1/2 - 3/4 inch thick, and cut into rounds with a scone cutter, or a handy glass, or whatever.
Lay on top of the fruit, dust with caster sugar, bake at 200˚C for about 30 minutes. Eat hot, ideally with lashings of double cream.
