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 30 minutes in a warm place.
Take the ball of dough, divide it into 4 equal pieces and leave to rest, covered, for 10 minutes. Shape into 4 long rolls place them on 2 baking sheets and leave to rest, covered, for 40 minutes.
With the aid of a knife, make 6 slashes on tops of the rolls. Lightly sieve some flour over the surface.
Put the rolls in an oven pre-heated to 230°C and bake for 30 minutes.
