In a bowl, combine the flour with salt and add the butter in small pieces
Mix lightly with your fingertips until you get a crumbly texture
Add the water (one tablespoon at a time) and knead until you form a ball
Wrap the dough in plastic wrap or aluminum foil and refrigerate for approximately 1 hour, or until it becomes firm
Open the dough on a floured surface and shape into a 20 cm diameter ring mold
Press the sides tightly so that the dough doesn't fall apart when baking
Make a few holes at the bottom with a fork
Place in a hot oven (220°C) preheated and bake for about 15 minutes or until golden brown
Let cool and unmold
Prepare the filling: In a small saucepan, whisk together the egg yolks, milk, and water over low heat, stirring constantly until it thickens slightly
Do not let it boil
Remove from heat, melt the gelatin in the remaining liquid, and add to the egg yolk mixture
Mix well to dissolve the gelatin
When the mixture has cooled slightly, add the other ingredients and mix well. Reserve
Beat the egg whites until stiff but not too dry
Add to the milk mixture carefully and place in the baked dough
