Cut butter into pieces. Put them in a pot with sugar and syrup. Heat while stirring, bring to the boil once, remove from the stove. Stir in ground almonds and spices. Dissolve the potash in approx. 2 tbsp. hot water, stir into the butter-syrup mixture and allow to cool. Sift the flour over the mixture and knead into a smooth dough, first with the dough hooks of the hand mixer, then with your hands
Cut the dough in half. Form one half into a roll (approx. 20 cm long, 5 cm Ø). Knead almond flakes under the other half. Form the dough into a rectangular piece (approx. 17 cm length, 3 cm height). Wrap both strands of dough in foil. Put them in a cool place overnight, better several days.
Cut whole almonds in half horizontally. Chop macadamia nuts. Cut dough into thin slices (the dough tends to break when cut) and spread on baking trays lined with baking paper. Decorate round cakes with prepared nuts
Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) one after the other for approx. 5 minutes
