Mix the flour and salt in a bowl.
Stir the water into the yeast and add to the bowl.
Blend with a spatula until you have a smooth dough and finish by kneading with a rolling pin.
Shape the dough into a ball, put it back in the bowl and cover with a cloth. Leave to rest for 80 minutes in a warm place.
Take the ball of dough and shape it into a long loaf. Place it on a baking sheet and leave to rest, covered, for 60 minutes.
With the aid of a knife, make a few slashes on top of the loaf to enable the dough to rise properly. Lightly sieve some flour over the surface.
Put the loaf in an oven pre-heated to 230°C and bake for 60 minutes.
