Step 1

Pre-heat the oven.

Step 2

Rub some oil around the inside of a 1kg/2lb loaf tin or insert a baking liner.

Step 3

Put the flour, bicarbonate of soda, Vitamin C if used, sugar and salt into a bowl, stir to combine and sieve into a mixing bowl.

Step 4

Measure the boiling water into a jug and add the cold water.

Step 5

Add the yogurt and lemon juice, if used, and stir to combine.

Step 6

Pour this into the mixing bowl and stir everything together to make a soft, sticky dough.

Step 7

Drizzle the oil over the sticky dough and using a spatula, turn the mixture a couple of times in the bowl to encourage the formation of a doughy mass.

Step 8

Tip the dough into the prepared tin and smooth the top.

Step 9

Brush some oil over a piece of tin foil. With the oiled side down, cover the tin creating a dome so the bread can rise during cooking.

Step 10

Bake for 55 minutes.

Step 11

Carefully remove the tin foil and bake for a further 10 minutes.
