Sift the flour and salt into a bowl and mix in the sugar.
Rub in the butter with your (clean) hands until a fine breadcrumb texture is achieved.
Form a well in the top of the flour, pour in the milk and water and mix well with a knife until the dough comes clean from the sides of the bowl.
Turn out onto a floured board and knead until smooth and silky, like a baby's bottom!
Shape into a moulded loaf, (some people cut a deep cross in the top) and bake in a preheated oven, 200C/400F for 25 minutes. Then lower the temperature to 180C/375F and cook a further 10-15 minutes until done. The loaf should be a light golden brown colour and sound hollow when tapped.
