1. To be prepared the night before.
Mix the flour, salt, sugar, whole eggs, melted butter, and yeast diluted in cold water. Work the dough well by beating it (if it sticks, add a little flour). It should remain soft. Place the covered and tightly closed container in the refrigerator.
2. The next morning, flour the work surface, shape the dough into a ball, and then roll it out with a rolling pin to form a square. Fold it in four and roll it out again. Then roll it into a log and cut it into 8 pieces. Place them in a large buttered and floured bundt pan. Let it rise in a warm place for about an hour.
3. When the dough fills the pan, bake in a hot oven (preheat the oven for about ten minutes), at 250°C (thermostat 8). Remove the brioche once it is golden brown.
