Place the saffron
in a heatproof jug and pour in the boiling water.
Leave to infuse until lukewarm.
Place the flour,
salt, yeast and olive oil in a food processor. Turn
on and gradually add the saffron and its liquid.
Process until the dough forms a ball.
Turn on to a
floured surface; knead for 10-15 minutes.
Place in a bowl, cover and leave to rise until
doubled in size, about 30-40 minutes.
Punch down the
dough and roll into an oval shape about 1cm/0.5 in
thick. Place on a lightly greased baking sheet and
leave to rise for 30 minutes.
Preheat the oven
to 200'C/400'F/Gas 6. With your fingers, press
indentations over the surface of the bread.
Cover with the
topping ingredients, brush lightly with olive oil,
and bake for 25 minutes or until the loaf sounds
hollow when tapped on the base. Leave to cool on a
wire rack.
