3. Stir in the cold water and lemon juice until the dough comes together.
4. Knead gently on a floured surface for about 1 minute until smooth.
5. Roll the dough into a rectangle, then fold it into thirds like a letter.
6. Chill in the refrigerator for 30 minutes.
7. Roll out again into a rectangle, fold, and chill for another 30 minutes.
8. Preheat the oven to 400°F (200°C).
9. Roll out the dough one last time, then cut into triangles.
