Place the sifted flour and salt into your food processor, add the cold butter cut into cubes, the sugar, salt, eggs, lemon zest, and pulse a few times until crumbly.

Remove from the food processor and work quickly with your hands (keep them cold by rubbing them on ice cubes) until smooth.

Wrap in plastic and allow to rest in the refrigerator for at least 1 hour.

If using fresh sour cherries, cook them (pitted) for 25 minutes on low heat with ½ cup of sugar and 4-5 tbsps water.

Combine the ricotta with the ½ cup sugar (and egg and liqueur if using: I don’t).

Preheat your oven to 350 F. Grease and dust a baking pan (I also like to line the bottom with parchment as an extra precaution).

Cut the dough into 2 pieces: one should be about 2/3 and the other 1/3 of the total volume.

Roll out the larger piece on a lightly floured counter and place it on the bottom and sides of the prepared cake pan; brush the bottom with the cherry jam and follow with the ricotta filling.

Some people do the opposite and spread the ricotta on the bottom, followed by the cherry jam on top: in this case the ricotta becomes colored by the cherries while the pie is baking.

Roll out the remaining dough into a smaller disc and use it to top the pie, sealing the edges (you can also decorate with strips, but the ricotta stays moister if you “close” the pie.

I cut it into a large flower shape, which I felt was large enough for this purpose). Bake for about 45-55 minutes.
