Cream the yeast with the sugar and add the warm water.
Sieve the flour into a large, warmed bowl, make a well in the middle and add the yeast liquid.
Push a little of the flour on top of the liquid and leave to sponge (bubble) for 10 minutes.
Now mix everything in the bowl very well, adding the salt and knead for 5 minutes.
Cover the dough with a damp cloth or greased cling film and leave to rise until doubled in size. (about 1 hour in a warm place).
Knock back and knead again, this time shaping the bread as desired and placing on a lined baking sheet. Meanwhile pre-heat the oven to 200C Fan/Gas 6.
Once the bread has doubled in size, carefully place into the pre-heated oven.
Bake for 35 - 40 minutes until the loaf sounds hollow when tapped on the bottom.
Leave to cool on a wire rack.
