Preheat your oven at 450F, and measure the dry ingredients and the fat into a mixing bowl.
Cut the dry ingredients and the fat until grainy (as shown in the picture) with a pastry fork.
When your oven has reached 450F, drop the water and the vinegar into the dry ingredients, and mix with a spoon until sticky.
Knead the sticky dough just enough to form a rough, lumpy ball.
Flatten the ball of dough and cut into 8 pieces.
Bake at 450F for 13 minutes.
Serve with butter as a side dish with your meals or with breakfast. Good results when re-heated in microwave!
