Brioche loaves with sourdough

This is a so enriched bread that I am not sure if the right name is bread or cake. It is so soft like a sponge and so melting into your mouth! If I have to put a name for this bread I'll call it the morning bread because seems to be perfect to put something over a slice and eat it in the morning.


Ingredients:

• 1000g flour
• 270g water (20ºC)
• 6 eggs + 1 (to brush the top)
• 150g liquid sourdough (100% hydration)
• 40g yeast
• 20g salt
• 50g powder milk
• 70g sugar
• 150g butter (room temperature)

Directions:

1. Mix all ingredients except butter using a standing mixer, first on a slow speed for 4 minutes and at a medium speed for 10 minutes.
2. Add butter and continue to mix for 4 minutes.
3. Cover the dough with a lid and let it raise for the bulk fermentation for 1h.
4. Take out the dough and divide it in 3.
5. Butter 3 pans and sprinkle a bit of flour on the bottom.
6. Shape the 3 loafs and put them in the pans.
7. Let them in a warm place covered with a towel for the final fermentation for 1h30. By the end of this time, the loaves should have been at least double in size.
8. Preheat the oven at 200ºC with a pan filled with lava rocks (or any type of stones).
9. Put the loaves in the oven and pour 100ml of water over the hot stones.
10. Bake for 35-40 minutes.
11. Take the loaves out of the oven, let them cool for 5-10 minutes and then remove the loaves out of the pans. Let them cool on a rack.
