Mix everything together in a bowl, and knead briefly by hand on a flour-dusted surface.
Divide the mixture in half, and slash with a knife across the centre and three or four along the top.
Bake in a hot oven for about 30 minutes.
Cool on a wire rack.
A hot oven is about 220-240 degrees celcius, or gas mark 7-8. My mum uses a turf-fuelled range!
You can also add a handful of sultanas or raisins to make it fruity.
Or substitute about 4 lb of the flour for wholemeal flour for a brown soda bread.
