Combine the yeast
and 75ml/5 tbsp of the water and leave to dissolve.
Mix the flours and salt in a large bowl. Make a
central well and pour in the yeast and water. Stir
from the centre to obtain a rough dough.
Transfer to a
floured surface and knead until smooth and elastic.
Return to the bowl and cover with a plastic bag.
Leave in a warm place until the dough has doubled in
size, about 1 1/2- 2 hours.
Grease a 23cm/9in
round cake tin. Punch down the dough and knead in
the sesame seeds. Divide the dough into 16 balls and
place in the tin. Cover with a plastic bag and leave
in a warm place until risen above the rim.
Preheat the oven
to 220C/425F/Gas 7. Brush the loaf with milk and
sprinkle with the sesame seeds. Bake for 15 minutes.
Lower the heat to 190C/375F/Gas 5 and bake until
the base sounds hollow when tapped, about 30
minutes. Cool on a wire rack.
