Mix the flour and salt in a bowl.
Stir the water into the yeast and add to in the bowl.
Blend with a spatula for 2 minutes, then add the poppy seeds and the diced Mimolette. Mix again 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 60 minutes in a warm place.
Take the ball of dough, divide it into 3 equal pieces and leave to rest, covered, for 10 minutes. Shape the dough into 3 long loaves, place them on a baking sheet and leave to rest, covered, for 2 hours.
Put the loaves in an oven pre-heated to 220°C and bake for 30 minutes.
