In a clean bowl mix the eggs, sugar, salt and whisk well.
In a blender mix the flour and cold butter until everything turns into crumbs. Transfer the flour crumbs into a clean bowl, add the eggs mixture and mix until it forms into a dough. Evenly distribute the dough on the bottom of a 10-inch pie pan and refrigerate for 30 minutes.
In a big bowl whisk the sugar and cornstarch together. Add the eggs and whisk again. Add the vanilla extract and give it a quick whisk then add the sour cream and whisk again until it has a smooth consistency.
Lay out half of the raspberries on the bottom of the pie dough and pour the filling over. Add the rest of the raspberries on top and bake at 350 degrees for about 50 minutes. Let it cool before slicing.
Notes
Instead of raspberries you can use any other berries you like.
