Combine the oil and buttermilk then mix into the flour mixture. Mix with a wooden spoon so that an even and moist dough is formed. Don't mix for too long.
With two teaspoons make 12 equal piles on a greased baking tray, spaced generously apart. Flatten the tops out a little but not too much; the bread rolls should look quite irregular! Sprinkle with a little sugar (demerara looks nice).
Bake in the preheated oven for 20 minutes until they are golden brown. Serve immediately.
