1. Rehydrate the yeast with a little water taken from the 400ml, let it sit for 5 minutes.
2. In a bowl, mix the flour with the yeast and salt, add the remaining water. Mix well until you obtain a nice dough ball.
3. Sprinkle the dough with flour, cover it with a towel and let it rest for at least 1 hour. The dough should double in size.
4. Shape the baguettes on a floured work surface.
5. Preheat the oven to 230°C (450°F) and place a dish filled with water at the bottom, then place the baguettes on top. The steam from the water will help achieve a crispy baguette.
