In a large bowl, combine flour and salt.
Add the chilled butter cubes and mix until the mixture resembles coarse crumbs.
In a separate bowl, combine cold water and lemon juice.
Gradually add the water mixture to the flour mixture, stirring until combined.
Turn the dough onto a floured surface and knead gently until smooth.
Wrap the dough in plastic wrap and refrigerate for at least 30 minutes.
Roll out the dough into a rectangle on a floured surface.
Fold the dough into thirds, like a letter, and refrigerate for another 30 minutes.
Repeat the rolling and folding process 2-3 times to create layers.
Once done, roll out the dough to your desired thickness and shape for your recipe.
