Prepare the first part of the dough. Chop the hardened margarine with a knife and mix it with a glass of flour. Form a ball from the mixture.

Prepare the second part of the dough. In a separate bowl, pour the remaining flour, add salt and lemon juice. Beat the egg in a glass and pour in water, then mix. Pour the egg into the flour and knead the dough, forming a ball.

Make puff pastry. Roll out the second part of the dough into a thick sheet and place the first one on it approximately in the center, a little closer to one of the edges. Wrap the dough like an envelope, seal the edges and put it in the refrigerator with the seams down for 30 minutes. Then roll it out again, fold it into an envelope and put it in the refrigerator for another 30 minutes. Repeat the procedure one more time.
