Preheat your oven to 220C / 200C fan / gas mark 7 / 425F. Dust a non-stick baking tray with a little flour.
In a large bowl, mix together the flours, salt and baking soda.
In a jug mix together the vinegar and milk.
Pour the milk/vinegar mixture into the dry ingredients and stir to combine.
Bring the dough together into a ball using your hands. The dough should just come together into a ball, but shouldn’t be wet and sloppy. If it doesn’t all come together add a splash of water. If it’s too wet and sloppy add a touch more flour.
Divide the dough into 4 roughly even balls and place on your prepared baking tray.
Flatten each ball a little and then cut a deep cross in each roll. The cross should go almost to the base of each roll – but not quite!
Bake the rolls in your pre-heated oven for 15-20 minutes until cooked all the way through and golden on top.
Ideally, serve warm – straight out of the oven!
