This recipe focuses on creating a classic, flaky quiche crust from scratch. Utilizing cold butter and lard, it guides you through mixing, chilling, and rolling the dough to achieve the perfect foundation for any quiche, ensuring a tender and crisp texture.
For a truly flaky crust, ensure all your fats (butter, lard) and liquid (milk) are very cold. This prevents the fats from fully incorporating, creating pockets of steam during baking. Avoid overworking the dough, as it can develop gluten and lead to a tough crust. Handle it just enough to bring it together. If the dough is too sticky, add a little more flour; if too dry, a tiny splash more cold milk. Blind baking the crust before adding the filling is crucial for a crisp base, preventing a 'soggy bottom'.
