Follow these simple steps to create your delicious Chocolate Croissants:

1. Prepare the Dough: In a large bowl, mix the flour, salt, and sugar. Add the cold butter pieces and use a pastry cutter or your fingers to combine until the mixture resembles coarse crumbs.
2. Add Wet Ingredients: In a separate bowl, mix cold water and lemon juice. Gradually add this to the flour mixture, stirring until a dough forms.
3. Chill the Dough: Shape the dough into a rectangle, wrap it in plastic wrap, and refrigerate for at least 1 hour.
4. Roll Out the Dough: On a lightly floured surface, roll out the chilled dough into a rectangle about 1/4 inch thick.
5. Fold the Dough: Fold the dough into thirds, like a letter. Then roll it out again into a rectangle and repeat this folding process twice more.
6. Cut the Dough: After the final fold, roll out the dough one last time. Cut it into triangles, approximately 4 inches wide at the base.
7. Add the Chocolate: Place a few chocolate chips at the wide end of each triangle. Optionally, add a small piece of chocolate for an extra gooey center.
8. Roll the Croissants: Starting from the wide end, roll the triangle towards the point to form a croissant shape. Tuck the ends slightly to create a crescent.
9. Prepare for Baking: Place the croissants on a baking sheet lined with parchment paper. Cover them with a kitchen towel and let them rise for about 30 minutes.
10. Preheat the Oven: Preheat your oven to 400°F (200°C).
11. Egg Wash: Beat the egg and brush it over the croissants for a golden finish.
12. Bake: Bake in the preheated oven for 20-25 minutes or until golden brown and flaky.
13. Cool: Allow the croissants to cool on a wire rack for a few minutes before serving.
