I have never eaten more delicious and aromatic croissants/brioches! I simplified this process as much as I could, but those who bake with sourdough starter understand why it's worth their time!
In total, you need:
50 g / 1.76 oz sourdough starter
400 ml / 14.10 oz of milk
150 g / 5.29 oz of sugar
550 g / 17.63 oz of flour
350 g / 12.34 oz of butter
1 teaspoon of salt
I leave the recipe here:
To activate the starter we need
50 g of starter (from the fridge)
50 ml of milk (temperature does not matter)
1 spoon of sugar
50 g of white flour for bread
Mix everything well, so that there are no lumps of flour, cover with a plastic film, and leave at room temperature for 2-3 hours. This sourdough starter will rise faster than the one with water.
When the starter has doubled its volume, it is ready to work!
Next we need:
150 g / 5.29 oz - of active sourdough starter
350 ml / 11.83 fl oz - of cold milk
100 g / 3.52 oz - of sugar
500 g /17.63 oz - of flour
1 teaspoon of salt
100g / 3.52oz - soft butter
For sheets
250g / 8.81 oz - frozen butter
In a bowl, put the sourdough starter, milk, sugar, mix actively, then add flour and salt, knead the dough until it becomes homogeneous, then add the soft butter, knead until you get a soft dough that does not stick to the hands. The dough is covered and put in the freezer for 12 hours, the butter is put in the freezer for 12 hours.
After 12 hours, remove the dough from the refrigerator, roll it into a rectangle. Grate the butter through a grater, and put it on top of the dough. Cover the butter well, so that it remains inside the dough. Wrap the dough at least 3 times. Then put it in the fridge for an hour. After an hour, roll the dough into a large rectangle, cut it in half, and then into triangles of equal sizes. Roll the triangles easily, without pressing them, place them on a tray lined with baking paper and let them rise for an hour at room temperature (covered with a towel). After you have noticed that the croissants have increased in volume, brush them with beaten egg and bake in the preheated oven at 200 C / 392 F for 45 minutes, until they are very well browned!
Let it cool completely!
Enjoy with pleasure!
