Get all the dry ingredients measured and in a large mixing bowl. Set that to the side to hang out for a few minutes.
In a small bowl separate your egg yolk from the white. We are only keeping the yolk, but feel free to keep the while for an omelet or something tomorrow.
To your egg yolk add the water and lemon, give it a mix and let it hang out next to your flour bowl.
Critical step! Make sure your butter is super cold, borderline frozen. Grate it, or cut it into super small pieces. I love using my kitchen aid grater attachment for this if you happen to have one.
Add the butter into your flour mixture, and using only your fingertips rub the flour into the butter pieces.
Next, create a well in the middle of your flour and add your water/lemon/egg soup.
Mix this as little as possible until it just starts to come together. Turn it over onto your countertop and kneed JUST until it forms a ball.
Lay down a layer of plastic wrap, add your dough and smush it down into a thick circular disk. Finish wrapping it up in plastic (I do a few layers) and chill for at least an hour (or overnight).
When ready to bake, roll the chilled dough on a floured surface with a floured rolling pin. If it cracks, let it sit on the counter a few minutes to soften, then fit it into your pie plate or tart pan.
Decide whether to blind bake: fillings that bake with the crust (like apple or pumpkin pie) need no blind baking. For pre-cooked, no-bake, or very wet fillings (quiches, custard or cream pies), blind bake the crust first so it doesn't turn soggy.
To blind bake: preheat the oven to 375°F. Line the crust with parchment paper or foil, covering the edges, then fill with pie weights, dried beans, or uncooked rice. Bake 15–20 minutes to set the crust.
Remove the parchment and weights, then return the crust to the oven for another 10–15 minutes, until golden and fully cooked. Cool completely before adding any no-bake filling.
For pies baked with their filling, skip the blind bake and follow your filling recipe's temperature and time (our pumpkin pie bakes about 45–50 minutes). Enjoy!
