Cooking
Step 1

Knead the dough. Mix water, vinegar, salt and egg in a bowl. Mix well. Start gradually adding flour, stirring gently. The dough should be tight, elastic and not stick to your hands. Place the dough on a floured table. Roll out a layer 0.5 cm thick. Grease with softened butter and roll into a roll. Then roll the roll into a tight "snail". This way you will get many layers with layers of butter. Cover the dough with film and put it in the refrigerator for 2 hours.
Step 2
While the dough is in the refrigerator, separate the yolk from the white and mix it thoroughly with a brush. Set aside.
Step 3

Roll up the croissants. Take the dough out of the fridge, flatten it a bit and roll it out with a rolling pin to a width of about 1 cm. Roll up the dough "envelope" to get 3 layers. Roll it out again. Sprinkle the dough with flour if necessary. Cut out triangles. Roll the triangles from the base to the top. Place on a baking sheet. Brush the top of the buns with yolk.
Step 4
Start baking the croissants. Place in the oven at 200 degrees and bake until golden brown, about 20 minutes.
Step 5
While the croissants are baking, prepare the filling. Mix cream cheese with Dijon mustard, olive oil and lemon juice. Mix until smooth. Cut the red fish into portions and separate the iceberg lettuce into leaves.
Step 6
Take out the finished croissants, cool, cut lengthwise into two halves. Grease with cream cheese cream, put a slice of fish and salad.
