Heat oven to 200C/180C fan/gas 6. Mix together the flour, salt and bicarb in a bowl. And if you’d like rosemary bread, add the chopped rosemary too.
Mix together the milk and lemon juice in a jug, and wait for a minute as it magically turns into buttermilk. Then stir in the honey, and simply pour it into the flour mixture. Stir it with a knife for a minute until the whole thing comes together into a sticky dough.
Tip onto a floured work surface and shape it into a ball.
Put the ball on a floured baking tray and, using a sharp knife, make a deep cross on top.
Put in the oven and bake for 40 mins.
Cool on a wire rack until warm, then slice and serve.
