Line a 1kg/2lb loaf tin, with parchment and pre-heat the oven.
Put the flour, bicarbonate of soda, Vitamin C and salt into a large bowl and mix together well.
Measure the yoghurt and water into a jug (add the lemon juice if used) and stir until combined.
Pour this into the mixing bowl and stir everything together to make a soft, sticky dough mass.
Tip the dough into the prepared tin, smooth the top and sprinkle with the oil.
Cover the tin with oiled tin foil creating a dome so that the can bread rise during cooking.
Bake for 55 minutes, carefully remove the tin foil and bake for a further 10 minutes.
Turn the loaf out onto a wire rack. The bottom should sound hollow when tapped.
Cool completely before slicing.

The recipe calls for far too little water, insufficient to make a dough. I added considerably more, sprinkled sunflower seeds on top and baked it. It looked fabulous, much more risen than in your photo.....but the loaf welds itself to the parchment paper liner. We'll end up cutting all the crust off. It's the first (and last) time I shall ever bake bread in a liner. Better to just grease a tin!
So your recipe needs a bit of adjusting.
