Dissolve the
yeast in the water with 5ml/1 tsp of the sugar. Sift
350g/12oz/3 cups of the white flour, the salt and
remaining sugar. Make a well and add the yeast, milk
and butter. Mix in gradually to form a smooth soft
batter.
Divide the batter
into two bowls. To one bowl, add 275g/10oz/2
1/2
cups of the strong white flour and mix together to a
soft dough. Knead until smooth. Shape into a ball,
put into a greased bowl and rotate to grease all
over. Cover with clear film.
Mix the treacle
and whole meal flour into the second bowl. Add enough
of the remaining white flour to make a soft dough.
Knead until smooth. Shape into a ball, put in a
greased bowl and cover. Leave the dough to rise in
a warm place for about 1 hour until doubled in size.
Grease two 22 x 11cm/8 1/2 x 4 1/2in loaf tins.
Preheat the oven
to 220C/425F/Gas 7. Punch down the dough and
divide each ball in half. Roll out half of the light
dough to a 30 x 20cm/12 x 8in rectangle. Roll out
half of the dark dough to the same size. Set the
dark dough rectangle on the light one. Roll up
tightly from a short side. Set in a loaf tin.
Repeat. Cover the tins and leave the dough to rise
until doubled in size. Bake for 30-35 minutes.
