Preheat the oven to 180°C (350°F).
Whisk together the egg yolks, sugar, and 2 tablespoons of water until light and frothy.
In a separate bowl, mix the flour and butter cubes with your fingers until the mixture becomes crumbly, resembling coarse sand.
Create a well in the center and pour in the egg mixture.
Quickly mix with a knife until the dough starts coming together—avoid overworking it.
Form the dough into a ball, press it down once or twice to smooth it out, and wrap it in plastic wrap. Chill for 30 minutes.
Roll out the dough to fit a 25 cm (10-inch) tart pan. Line the pan with the dough, trim the edges, and prick the bottom with a fork.
Cover with parchment paper and fill with baking beans or rice.
Blind bake for 20–25 minutes or until lightly golden. Remove the beans and let cool. Reduce the oven temperature to 150°C (300°F) for the meringue step.
