Knead the cold butter, sugar, flour, salt, and egg into a smooth shortcrust pastry. Wrap the dough in plastic wrap and let it rest in the refrigerator for at least 30 minutes.
02 -
Line a springform pan with parchment paper and grease the sides well. Secure the parchment paper by clamping it in place so it doesn't shift later.
03 -
Roll out the chilled dough thinly using some plastic wrap to help, and place it in the form. Create a nice edge by pressing the dough up the sides to prevent the filling from overflowing later.
04 -
Allow frozen raspberries to thaw slightly, or wash and drain fresh raspberries.
05 -
For the filling, mix the pudding powder with sugar and milk in a pot until smooth. Bring to a boil over medium heat, stirring constantly, until the mixture thickens.
06 -
Remove the pot from the heat and transfer the pudding to a bowl. Cover the surface directly with plastic wrap to prevent a skin from forming. Let the pudding cool slightly, then gently fold in the sour cream.
07 -
Spread the sour cream mixture evenly over the pastry base and smooth it out. Then distribute the raspberries over the top.
08 -
Bake the cake in a preheated oven at 350°F (180°C) conventional heat for 45-60 minutes, until the edge is golden brown and the filling still has a slight wobble.
09 -
For more shine, prepare the clear cake glaze according to package instructions and spread it thinly over the raspberries. This will also help keep the raspberries fresh longer.
10 -
Allow the cake to cool completely and preferably chill overnight in the refrigerator so it cuts more cleanly.
