Rock Buns

This is my grandmother's recipe and I'm not sure how far back it goes before that. She gave it to my mum, who gave it to me. These warm spicy buns with mixed fruit are a perfect winter treat.
Who doesn't love some spicy, rock-hard buns? ;)

Rock Buns
8oz self raising flour
3oz margerine
3oz castor sugar
3oz mixed dried fruit
1 medium egg
1 level teaspoon of mixed spice
2 1/2 oz milk

Put flour, egg, margerine and mixed spice into blender. Mix till crumbed.
Pour into a baking bowl and mix in fruit.
Add milk and egg and mix lightly into a fairly rough dough (do not over mix)
Using a fork, deposit onto greased baking tray in small rock-like heaps
Sprinkle lightly with castor sugar
Bake at 220C near top of oven for 15mins

Remove from oven and allow few minutes for buns to set (should be crisp on outside)
Serve warm with or without butter.
