Roll out the dough into a rectangle that is about. 20 cm x 60 cm. (1 width x 3 length in size)

Grate the butter over the dough rectangle.

Fold #1

Fold a letter-fold for 3 layers and a neat square.

Let dough rest 15-30 minutes in the refrigerator.

Roll out to a new rectangle that has a 1 x 3 size again.

Fold #2

Fold a letter-fold for 3 layers and a neat square.

Let dough rest 15-30 minutes in the refrigerator.

Roll out the rectangle that has a 1 x 3 size again.

Fold #3

Fold a letter-fold for 3 layers and a neat square.

Let dough rest 15-30 minutes in the refrigerator.

The dough has now 3x3x3 layer. That is 27 layers of butter evenly distributed.





Shaping

Roll out the dough to 16" x 24" (40 cm x 60 cm).

Trim the edges so they're equal and straight.

Cut it in the middle length-ways so you have two equal halves that are 8" x 24" (20 cm x 60 cm).

Cut each half into four equal squares of 8" x 6" (20 cm x 15 cm).



For croissant

Cut each square into two triangles by cutting from corner to corner.

Gently pull the triangles slightly long and roll them from the wide end against the tip. you should end with 3 layers.





For pain au chocolat

Cut each rectangle in the middle so you end up with pieces of 4" x 6" (10 cm x 15 cm).

Place two strips of chocolate in the middle of the narrow part, then place two more in the middle of that and the end. With approx. 1½" (4 cm) intervals.

Roll the dough together around the chocolate..

Final rise

Put 8 of them at a time on a baking pan+baking sheet. They must rest on the rolled up tip.

Let them rise until doubled in size from ½ to 1 ½ hours. They may not withdraw where there is so hot that the butter to melt. Then in the summer it may be necessary to take them in and out of the fridge.

When they are raised then brush them with beaten egg and what fluid you are now using.

Baking

Convection: bake approx. 20 minutes at 180°C (360°F)

Normal oven: bake approx. 20 minutes at 200°C (400°F)

Let them cool for at least 20 minutes before consuming.

Notes

If you want to understand the process better, then read my article on the principles behind a laminated dough. It has tons of pictures There you can also see different variations of the method that you can experiment with to make "your own style" croissants.
