This is a simple and fast bread to make fresh for breakfast. The bicarbonate of soda is activated by the acidity of the buttermilk. If you like you can add mixed seeds, chopped fresh herbs or olives, sundried tomatoes, dried fruit or chorizo. You can also make it without the oat flour; just make it up to 250g flour in total.
1. Preheat the oven to 220°C/200°C fan/gas mark 7. Line a baking tray with baking parchment and dust liberally with flour.
2. In a large bowl, measure the flours, xanthan gum, bicarbonate of soda, salt and sugar, and mix well so they are evenly combined.
3. Pour the buttermilk over the dry ingredients and stir in enough milk to form a thick, sticky dough.
4. Tip the dough out onto the floured baking parchment; it will still break and crumble. Coat your hands in flour if the dough is sticky, and lift the dough and turn it to shape it into a ball, rather than kneading it. This will help to give the bread a soft, melting texture.
5. When you have a fairly smooth ball, pat the top with the oats or wholegrain flour, transfer to a baking tray and then flatten the top slightly. Leave in a warm place for 15 minutes to rise.
6. Use a sharp knife to score the bread into four, cutting almost through to the base, and taking care not to knock the air out.
7. Bake for about 40 minutes until golden brown and cooked through: tap the bottom and it should sound ‘hollow’. Set aside to cool on a rack and enjoy warm and fresh on the same day, or freeze.
You can make individual soda breads in a muffin tin. Weigh out about 75g of the dough onto a square of baking parchment. Drop the dough into 8 holes of a muffin tin and then bake for 30 minutes, or until nicely browned on the top and sides.
