Protein content in flour controls how much gluten can form when the dough is mixed with water. Gluten is the stretchy network that gives dough its structure and chew. The more gluten-forming proteins (gliadin and glutenin) present, the stronger the gluten network becomes, making the dough tougher and less tender. In pastry work, you want less gluten development so the dough stays tender and can be rolled or laminated into delicate crusts, which is helped by using flour with lower protein content and by using fats to coat flour particles and limit gluten formation. So, higher protein flour (bread flour) creates more gluten and a tougher dough, while lower protein flour (pastry flour) yields a tender, and often flakier, crust.
