For the dough: In a bowl, mix the yolk, sugar and water.
In a separate bowl, add the flour and salt and place the butter cubes on top. Mix with your fingertips until combined and crumbly. Make a hole in the middle and add the wet ingredient mixture, kneading with the palms of your hands to combine. Wrap in plastic wrap and refrigerate for at least 1 hour.
Prepare a springform pan with parchment paper and butter. On a floured surface, use a rolling pin to flatten the dough. Place the dough in the prepared pan and pierce the bottom with a fork.
For the filling: Preheat oven to 350 degrees. In a mixing bowl, beat the eggs with a pinch of salt and the heavy cream. Add the cheese. Set aside.
In a frying pan over medium-high heat, add the olive oil. Add onion and garlic and saute until fragrant.
Add the shrimp and sauté until golden. Season with salt and black pepper. Turn off the heat and add the parsley. Set aside to cool slightly. Add shrimp mixture to egg mixture and stir to combine. Pour into prepared pan, and add dollops of cheese around the top. Bake for 40 minutes. Slice and serve.
