Grease the bread tin(s). Place the flour, salt, yeast and fat into a large mixing bowl. Mix the fat through the flour and make a well in the centre of the flour mixture.
Add most of the water to the well, keeping a little in reserve, and mix to a soft dough. Add the remaining water if necessary.
Tip the dough onto a table and knead for 8-10 minutes.
Place the dough back into the bowl and cover with oiled cling film or a damp tea towel. Rest in a warm place until the dough doubles in size. This will take approximately 45 minutes.
Split the dough into two pieces if desired. Mould the dough round and fold to the shape of the tin(s). Place the dough piece into the tin, seam down, cover with oiled cling film or a damp tea towel. Put in a warm place and allow to rise about 1cm above the tin. This will take 45-60 minutes.
Uncover and bake in a preheated oven, 220°C fan/240°C/430°F/Gas 8. Bake small loaves for 20-25 minutes or a large loaf for 30-35 minutes.
Remove the loaf from the tin. Check it is baked by tapping the bottom of the loaf - it should sound hollow. Place on a wire rack to cool.
For pizza: follow this recipe, using olive oil not fat. Reduce to prove to 30 minutes. Roll dough into 3 thin rounds. Place on baking sheets. Add sauce and toppings. Bake at 22C for 10-14 minutes
