Method

1. Preheat the oven to 220C/gas 7. Brush a baking tray generously with olive oil.

2. Sieve the plain flour and the bicarbonate of soda into a big bowl, add the salt, 50g of the cheese and mix together with your hands.

3. Make a well in the centre of the dry ingredients and pour in most of the buttermilk. Spread the fingers of one hand out like a claw and together in a full circle. Add enough of the remaining buttermilk to make a soft dough. Do not knead the mix, but work it very gently to bring together.

4. Place the dough onto a floured surface and roll out to about 35 x 20cm. Transfer the rolled dough to an oiled baking tray, brush the top with some more oil and sprinkle with the remaining cheese. Bake for 18-25 minutes, turning the oven down to 200C after 10 minutes. When cooked the bread should be a golden brown colour and feel firm in the centre. Transfer it to a wire rack and cool for a couple of minutes, then cut it into squares and serve.
