Mille-feuille with Dulce de Leche Homemade and crispyIngredients

Preparation:
1. Prepare the dough:
Place the flour in a bowl and add the salt, water, melted butter, and vinegar.

Mix until all the ingredients are combined and knead for 5 to 7 minutes, until you obtain a smooth and homogeneous dough.

Wrap the dough and let it rest in the refrigerator for 30 minutes.

2. Prepare the butter mixture
Mix the cold butter with the 50g of flour until a smooth paste forms.
Shape it into a rectangle, wrap it, and refrigerate for a few minutes to firm up.

3. Make the puff pastry turns
Roll out the dough into a rectangle and place the butter mixture in the center.
Fold the dough over the butter until it is completely covered.
Carefully roll it out again into a rectangle. Make a single turn: fold one-third of the dough towards the center and then fold the other third over.
Refrigerate for 20 minutes.
Repeat the rolling, folding, and resting process 3 more times, always letting the dough chill between each turn.
