Mix the yeast
with the flours in a large mixing bowl. Melt the
butter. Then stir the warm water, milk, sugar,
butter, salt, sesame seeds, onion and rosemary into
the flour. Knead thoroughly until quite smooth.
Flatten the
dough, then add the cheese cubes. Knead them in
until they are well combined.
Place the dough
into a clean bowl greased with a little melted
butter. Cover with a dish towel and put in a warm
place for 1 1/2 hours, or until the dough has doubled
in size.
Grease a 23 x
13cm/9 x 5in loaf tin with butter. Punch down the
dough and shape into a loaf. Place in the tin, cover
with the dish towel and leave for about 1 hour until
doubled in size. Preheat the oven to 190C/375F/Gas
5.
Bake for 30
minutes. Cover the loaf with foil for the last 5-10
minutes of baking. Turn the bread out on to a wire
rack to cool. Garnish with some rosemary leaves and
coarse salt scattered on top.
