Preheat your oven to 190ºC/375ºF/Gas mark 5

Grease & line a baking sheet with parchment paper

In a large mixing bowl, combine the flour, oatmeal, bicarbonate of soda, cream of tartar and salt

Rub in the butter

Make a well in the centre and pour in the buttermilk. Bring the mixture together to form a dough ball. Don't over-mix

Place the ball on to a well-floured worktop and divide into 6 equal pieces

One by one, lightly roll each piece into a ball and dip the 'top' of the ball into the seeds. If necessary, spritz the balls with water to help the seeds stick to the surface

Put the balls on the prepared tray, score the top of each ball with a cross and bake for 30-40 minutes until the tops are brown and well risen

Allow to cool on a wire rack. Eat warm
