Cream butter, salt, vanillin sugar and sugar. Stir in the eggs one after the other. Stir in bitter almond flavour. Mix flour, starch, almonds and baking powder. Stir in portions. Pour into a piping bag with a star-shaped spout (15 mm Ø) and squirt strips (5.5-6 cm long; keep a little distance as they run apart) onto 3 baking trays lined with baking paper.
Bake one after the other in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: stage 2) for 18-20 minutes.
Remove from the oven, place on the cake rack and allow to cool. Coarsely chop the chocolate coating and melt it over a warm water bath. Dip the thicker side of the cookies into the couverture, drain and place on baking paper.
Sprinkle with sugar pearls and let dry. Store in tins.
