Cream together 150g butter and 1 egg until pale, then mix in 150ml soured cream with salt and baking powder to form a soft dough with 400g flour. Chill for 30 minutes, then divide into two portions and roll out thinly. For the filling, mix 500g curd cheese with 100g sugar, 1 egg yolk, and vanilla extract until smooth, then fold in 100g jam. Place the cheese mixture on one pastry sheet, cover with the second sheet, and seal edges with water. Brush with beaten egg and bake at 180C for 35-40 minutes until golden brown. Cool slightly before cutting into squares or diamonds.
