1. Combine 350g stone ground wholemeal flour, 50g plain white flour and 1 level tsp each of bicarbonate of soda, salt and brown sugar in a mixing bowl.
  2. In a small bowl, whisk together 1 large free range egg, 1 rounded tbsp treacle and 400ml buttermilk.
  3. Add to the mixing bowl and mix with a wooden spoon until combined.
  4. Transfer into a greased and lined 2lb loaf tin. Slash the top along the centre with a knife so that it will crack evenly while cooking.
  5. Bake at 200˚C/180˚C fan/gas mark 6 for one hour, until the bottom of the bread sounds hollow when tapped and a skewer inserted in the centre comes out clean.
