- 1/3 cup whole milk, lukewarm
- 2 1/4 teaspoons (1 packet) active dry yeast
- 4 large eggs, divided
- 3 tablespoons sugar
- 3/4 teaspoon salt
- 3 cups bread flour
- 1 cup (2 sticks) unsalted butter, softened
- In the bowl of a stand mixer with the dough hook attachment, dissolve the yeast in the milk and let stand until it starts to foam, about 10 minutes
- Add three of the eggs, the sugar, and the salt and mix on low speed to combine, about 30 seconds
- Add the flour and mix on low speed until the dough comes together and forms a ball, about 4 minutes
- Increase the speed to medium and gradually add the butter, one tablespoon at a time, waiting until fully incorporated before adding the next piece. Pause to scrape down the bowl as necessary. This should take no less than 10 minutes
- Continue to mix the dough on medium speed for a further 15 minutes, until the dough is smooth and begins to slap the sides of the bowl
- Transfer the dough to a large, lightly buttered bowl and cover with plastic wrap and refrigerate overnight or for 8 hours. Refrigerating overnight ensures the best flavor, but you may skip this step and instead let the dough rise at room temperature until doubled in size, about 1 hour
- Grease a loaf pan generously with butter
- In a small bowl, beat the remaining egg with a tablespoon of water to make an egg wash
- Remove the dough from the refrigerator and divide it into eight equal pieces. Shape each piece into a ball and place them in the loaf pan in two rows of four with the seam-side down. Brush lightly with egg wash, then cover with plastic and let it proof until almost doubled in size, about 1 to 1 1/2 hours
- Preheat the oven to 375 degrees Fahrenheit
- Remove the plastic and gently brush the dough with another coating of egg wash. Bake for 30 to 35 minutes, until it turns a rich, golden brown
