Instructions
Day 1
Prepare a leaven. Mix flour, water and leaven in proportion 1:1:1 and let it rise for 5-6 hours at 24-26℃.
When the leaven is ready, mix all the ingredients in a bowl.
Knead the dough 5 mins until a smooth ball is formed.
Proof the dough covered at temperature 26° C, 1-2h.
Then, put the dough covered into the fridge overnight.
Day 2
Fold a parchment paper in half and measure a rectangle, sized 15x20 cm.
Cut the butter for lamination (130g) into a rectangle 15x20 cm. Roll out the butter to have the same thickness and cool down in the fridge for at least 1 hour.
First Set of Lamination:
Take the dough out of the fridge and roll it into a rectangle sized 15x30 cm.
Take the butter out of the fridge and give it 5 mins to warm up a little bit. Place the butter over ⅔ dough and lock the butter in. Roll out the dough and do a double fold (book fold).
Cool down and relax the dough for 15 mins in the fridge.
Second Set of Lamination:
Take the dough from the fridge. Roll out to 25x50cm. Do a single fold (letter fold). Rest 1-2hr in the fridge.
Roll out 25x60cm. Cut into triangles of 10x25cm, roll into croissants.
The final proof overnight, t 26-28°C. The Croissants should be cloudy and jiggle when you shake the tray.
Day 3
Egg wash the croissants before baking. For the eggwash I use 1 quail egg and a table spoon of milk.
Bake at 180°C for 25 mins using the Convection type of cooking.
Remove your hand-laminated, 100% sourdough croissants from the oven. Let them cool down a little bit while you're making a cup of coffee.
