Melt butter, brown lightly and let it cool in a bowl. As soon as it is firm again, stir until frothy, adding sugar, the contents of the packet "Fine Orange Fruit" and salt.
Add 1 tablespoon of liqueur and finally knead in the flour. Form 2 rolls of about 24 cm length and 21/2 -3 cm Ø. Brush with egg white and turn in chopped almonds. Put the rolls in a cool place for at least 1 hour.
Use a sharp knife to cut into approx. 1/2 cm thick slices and spread them on 2 baking trays lined with baking paper. Bake in the preheated oven (electric cooker: 200°C/ gas: level 3) for about 10 minutes.
Let it cool down. Wash the orange thoroughly in hot water, dab dry and peel the peel in fine strips with a julienne shredder. Halve the fruit and squeeze the juice out of one half. Mix icing sugar, remaining orange liqueur and 1-2 tablespoons of orange juice to a smooth glaze.
Spread the cookies with a brush and sprinkle with orange julienne. Leave to dry.
