Step 1

Preheat the oven to 375ºF

Step 2

Add the flour, powdered sugar, baking powder, lemon zest and salt to the bowl of a food processor, and pulse until well combined.

Step 3

Add in the butter and pulse 5-7 times, or until the butter is broken down into tiny pebbles.

Step 4

With the motor running, add in the eggs and let the dough process until it forms together into a cohesive ball around the blade, about 1 minute.

Step 5

Transfer the dough to a work surface dusted with flour. Divide the dough in half.

Step 6

Roll out half of the dough to a rough 11″ circle and place inside of a 9″ deep-dish pie plate, tucking the ends of the pastry underneath themselves to form an edge. Pierce the bottom of the pastry multiple times with a fork to allow the steam to escape when baking. Place the pastry in the freezer to chill while the oven preheats, or at least 10 minutes.

Step 7

Roll out the other half of the dough to a rough 10-inch circle. Place the pie dough on a flat surface (such as a sheet pan) that can fit in your refrigerator. Cover, and transfer to the refrigerator to chill.

Step 8

Remove the bottom crust from the freezer and line the pastry with a round piece of parchment paper and then add pie weights to fill (or dry rice or beans or lentils), making sure to push pie weights up against the edges. Bake for 20 minutes on the lower rack, then remove from the oven and remove the parchment and pie weights. Return to the oven and bake for an additional 5 minutes.

Step 9

Remove from the oven and let cool for about 15 minutes.

Step 10

Meanwhile, make the filling: Add the (strained) ricotta to a large bowl. Whip it with a whisk for 30 seconds until lightened. Add the sugar, eggs, lemon juice, lemon zest, and almond extract and whisk together until well combined.

Step 11

Transfer the filling to the slightly cooled pie shell.

Step 12

Whisk together an egg with a bit of water to make an egg wash.

Step 13

Remove the rolled-out top crust from the refrigerator. Score the top crust with the fork in a lattice pattern by evenly pressing and dragging the fork on the pastry. You want to get a good score on it, but make sure not to cut through the pastry.

Step 14

Brush the egg wash on the top crust as well as on the edges of the baked bottom pie crust (this will help the top crust seal to the edges). Transfer the top crust pastry on top of the ricotta filling. Seal the top crust into the edges, and cut off any excess dough.

Step 15

Bake the pie on a rimmed baking sheet in the middle part of the oven for 40-50 minutes, or until the top is golden and shiny and the filling has just nearly puffed up throughout, leaving just a small portion in the middle that has not risen.

Step 16

Let cool for at last 2 hours. Serve at room temperature or cold.
