Mix flour, salt, egg yolk, 25 g butter and 150 ml water to a smooth dough and chill for 15 minutes. Beat 250 g butter with a little flour flat to make a square. Roll out the dough on a floured work surface to a square, twice the size of the fat. Place the fat on top, fold the dough corners over it so that no more fat is visible. Roll out the fat into a rectangle and fold over twice from the long side.
Roll out the dough again and fold over three times. Chill the dough for 15 minutes and repeat the process. Refrigerate dough for 30 minutes. Divide dough and roll out 2 rectangles of 30 x 24 cm. For the filling mix sugar, almonds, egg yolk, lemon juice and zest. Place one pastry sheet on a wet baking tray, spread the filling on it and place the second pastry sheet on top. Brush the edges with water and press together. Prick several times with a fork and brush with egg yolk. Bake in the preheated oven (electric oven: 225 ° C/ gas: level 4) for 20-25 minutes. Take out the cake and brush with the jam while still hot.
