Put flour, salt, vanillin sugar, baking powder, sugar and almonds into a mixing bowl and mix. Add the butter in flakes and the egg and mix to a smooth dough using the dough hook of the hand mixer. Cover the dough and chill for about 30 minutes
In the meantime draw a pig's head on a sheet of paper as a template (8.5 cm Ø). Roll out the dough on a lightly floured work surface to a thickness of approx. 5 mm and cut out pig's heads using the template. Fold the right ear to the front and press it slightly. Knead the remaining dough and cut out 12 circles (approx. 2.5 cm Ø). Use a nozzle (0.5 cm Ø) to cut out 2 circles each as nostrils. Beat the egg white. Spread one side of the circles with the egg white and stick them on the heads as noses. Place on a baking tray lined with baking paper and bake in a preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for 20-25 minutes until golden brown. Let the biscuits cool down on a cake rack
Stir icing sugar, lemon juice and food colouring until smooth. Apply the icing with a brush. Leave the nostrils free. For the eye, press one sugar bead each into the icing, allow to dry
Waiting time approx. 1 hour
