For the dough, place the fat, icing sugar, flour, 1 egg and 1 pinch of salt in a mixing bowl. Mix with the dough hooks of the hand mixer. Then work into a smooth dough with your hands. Wrap in foil and chill for about 30 minutes. In the meantime, season the topping with milk, vanilla pulp, sugar, 1 pinch of salt and lemon zest. Bring to the boil.
Sprinkle in semolina while stirring constantly, bring to the boil again. Separate 4 eggs. Beat the egg whites until stiff. Stir egg yolk and 2 tablespoons of water until smooth. Stir the beaten egg yolk and poppy seed baking into the semolina mixture. Fold in the beaten egg white. Warm up the jam. Roll out 2/3 of the dough on a floured work surface and line the fat pan of the oven (32 x 38 cm) with it. Spread with jam. Spread poppy seed mixture on top to smooth it down. Roll out the rest of the dough and roll out approx. 1 cm wide strips. Place as a grid on the poppy seed mixture.
