Grind the cookies (using a blender). Melt the butter and stir in the crumbs. Spoon the mixture into a round shape (20-22 cm) with removable sides and distribute evenly, pressing down to the bottom of the pan. Cover with cling film and refrigerate.
The gelatin must first be soaked in cold water.
Filling! Cottage cheese + sugar + lemon zest + vanilla sugar + sour cream = everything needs to be chopped with a blender. Pour gelatin in a thin stream into the curd mass. Mix thoroughly until smooth. It is advisable to use a mixer or blender.
Gently pour the curd mixture onto the cookie base and smooth the surface. Place the cheesecake pan in the refrigerator for 2 hours.
