In a big bowl add the following ingredients:

• 1 egg white – keep the yolk for later
• 660 grams of Flour
• 1 teaspoon of salt

Mix well the flour and the rest of the ingredients. The dough will be sticky.

On a flat surface pour some cooking oil and transfer the dough from the bowl to the surface for easier kneading. Knead it well in different directions for couple of minutes. Form a ball from the dough and put it back into the bowl.

1 hour – leave it to rest.

It should double its volume. Transfer the dough from the bowl to the flat surface and knead the dough for a minute.

• Divide the dough into 12 equal parts.
• Spread each of them into a flat circle.
• Stack them while covering each with a melted butter except for the top one.

30 – 40 min. – leave it to rest

• Transfer the dough to the flat surface and spread it until it makes a circle with diameter of 50 cm.
• Use a pizza cutter or a similar tool to cut the circle into 12 equal parts
• roll each part as shown in the video to form each croissant
• Put a baking paper at the bottom of the baking pan and arrange the croissants on top of it

20 min – leave it to rest

• Add a little bit of milk to the egg yolk
• mix it well
• use a brush to cover the croissants with the mix

Pre-heat the oven to 180 degrees Celsius (360 degrees Fahrenheit)

Bake for 20 to 30 min.

Take the pan out of the oven and let the croissants cool of. Cover the pan with aluminum foil, so the croissants do not dry up.

You are done – enjoy!
