step 1
In a large bowl, mix together the flour, (optional sugar) and salt, rub in the butter or margarine and then stir in the yeast.
step 2
Stir in the water and mix into a soft dough by hand.
step 3
Knead the dough for about 5 minutes in an electric mixer fitted with a dough hook, or turn out onto a floured surface and knead well for 10 minutes by hand.
step 4
Shape the dough, then place in a greased 2lb tin or on a baking tray. Cover with a clean, damp tea towel. (this stops the dough drying out) and leave in a warm place until doubled in size (1:1/2-2 hours).
step 5
Uncover and bake in an oven, preheated to 230C (450F, gas mark 8) for 30-35 minutes.
step 6
Take the loaf out of the tin and cool on a rack. (the baked loaf should sound hollow when tapped underneath)
