1. Put the water and flour in the bowl of a stand mixer and knead for a few minutes on low speed to mix well.
2. Cover the bowl and let the dough rest for 30 minutes.
3. Add the salt and yeast and knead for 5 minutes on medium speed. Cover the bowl and let the dough rest for 30 minutes.
4. Perform a fold: fold the dough over itself from one side and then the other. Let it rest for another 30 minutes.
5. Divide the dough into 4 equal pieces using a dough cutter, then quickly shape them. Cover with a clean towel and let them rest for 30 minutes.
6. On a lightly floured work surface, shape each piece of dough into a baguette shape. Do not stretch them too much and make sure they do not exceed the size of the oven. Place the shaped baguettes on a baking sheet lined with parchment paper.
7. Cover them and let them rest for 30 minutes.
8. Preheat the oven to 240°C (464°F) with the baking tray on the bottom.
9. Score the baguettes quickly to create the slashes and place them in the oven, pouring a bowl of hot water into the baking tray.
10. Bake for 15 minutes.
