Preheat the oven to 200°C/ 180°C fan/ gas mark 6/ 400°F. Put a baking sheet or a baking/pizza stone in the oven to heat
Mix the dry ingredients. Stir in the milk, then bring the dough together by stirring the ingredients until it forms a dough. It's easiest to do this with your hands
Turn the dough out onto your work surface and knead briefly until the dough has a uniform consistency. See post above for kneading instructions
Shape the dough into a round disc about 2-3cm thick (1-1½ inches). Score the top with a deep cross. Don't make it thicker or it won't cook in the middle
Bake on the hot stone or baking sheet for about 35 minutes until light brown. Remove the bread and tap on the bottom - if it sounds hollow, it's done. If not, leave for another 5 minutes.

Notes
If you don't have milk you can make some up with powdered milk or half-and-half yogurt and water.
