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 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 190oC/375oF/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.
