6. Remove the pan to a rack.
7. Make the pastry.
8. Place the flour and salt in the bowl of a food processor and pulse to combine.
9. Add the butter and pulse until the mixture resembles coarse cornmeal, about 13 to 15 one-second pulses.
10. With the machine running, add the ice water and process just until the dough starts to come together.
11. Dont over-mix.
12. Transfer the dough to a lightly floured work surface and form into a disc with your hands.
13. Roll out the dough into a 13-inch circle, then ease it into a 10-inch tart pan, fitting it snugly against the sides and bottom, and trim the excess.
14. Prick the bottom of the tart with a fork and refrigerate for 30 minutes.
15. Make the filling.
16. Whisk the ricotta, egg yolk, and olive oil in a small bowl until smooth.
17. Stir in the creme fraiche and season with salt and pepper.
18. Set aside.
19. Make the royale.
20. Whisk the egg, flour, and salt in a small bowl.

23. Set aside.
24. Bake the tart.
25. Raise the oven temperature to 375F (190C).

30. Dot with the remaining onions.
31. Bake the tart for 30 minutes, rotating 180 degrees after 15 minutes.
