I use a rectangular tart pan with a removable bottom, but it can also be made in an 8-inch round or square pie pan with removable bottom.
Preheat the oven to 350ºF/180°C.
Cream ½ cup + 1 tablespoon unsalted butter in a large bowl with a spatula until smooth. Add ¾ cup powdered sugar and mix until incorporated.
Add 1 egg and mix with the spatula or a fork. It will not be smooth or completely incorporated and that is fine.
Add 1 cup flour and pinch salt. Mix it, but don’t wait until the flour is completely incorporated and add the remaining ¾ cup flour. Now, mix it until it's mostly incorporated. Use the spatula to slide and fold the dough. A few dry spots might remain.
Turn the uneven dough onto a clean surface or counter and mix with your hands, trying to make it come together but handling it as little as possible. The more you handle it, the softer the butter gets and the tougher the crust will be after it's baked. So, a quick, light touch is the best. Don't knead it like you would bread.
When you have a smooth dough ball, wrap it in plastic and refrigerate for at least 1 hour and up to 2 days. While the crust is resting, you can make the almond cream.
When ready to roll, take the dough from the fridge and let barely soften at room temperature. The dough must still be cold. Simply wait until you can start to roll it, but not until it is very soft. This is important to ensure a tender dough.
On a lightly floured counter, start rolling the dough disc, making sure you do quarter turns (I do them to the left) often to ensure the dough is not sticking and adding more flour to the counter if it is sticking.
Once you have rolled the dough a few inches larger than the pan, fold it in half and place it in the middle of the pan. It's soft, so handle with care.
Open the dough and line the pan, being careful not to stretch the dough. Use your hands to lower the dough and reach the union between the bottom and sides of the pie pan. If it tears, press it back together with your fingers and pat an extra piece of dough (from the scraps) if necessary.
Go over the rim of the pan with the rolling pin to remove excess dough.
Prick the bottom with a fork, freeze for 20 minutes, or put it in the refrigerator for 1 hour. At this point, you can leave the dough frozen in the pan, wrapped in plastic, for up to a month.
How to prepare a pie crust for blind baking: take out the cold, lined pie pan from the fridge or freezer. Cut a piece of aluminum paper that is larger than the tart pan. Line the inside of the pan by covering the cold dough with it and adjusting it so that it takes the shape of the dough. You can also use parchment paper, but it's usually coarser and more difficult to make it take the shape of the pan and cover the dough well. Add weight. I use round ceramic weights that you can buy online, but you can add any raw grains and legumes such as beans, lentils, rice or even flour (simply fill the aluminum paper with flour or rice or whatever you're using until you have added a layer of weight that will be enough to keep the paper down during baking. Bake for 15 minutes. It might be a few minutes more or less depending on the type of pie crust, but the idea is to let the dough bake and dry out enough so that we can lift the aluminum paper without it attaching to the raw dough. The paper should lift easily and the dough below will be half baked, very lightly golden. Fill and bake further following instructions in the recipe for the tart or pie you're making.
