Knead the flour, 50 g sugar, salt, egg and 100 g butter in flakes first with the dough hooks of the hand mixer, then with your hands to a smooth dough. Form into a roll (16 cm long; 5 cm Ø) on a floured work surface. Wrap in foil and chill for about 1 hour. Cut into 20 slices. Press a little larger with your hands (6 cm Ø).
Place on 2 baking trays lined with baking paper. Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 8-10 minutes. Let them cool down. Wash the macadamia nuts and rub them dry well. Spread the nuts over the talers. Heat 300 g sugar, 75 ml water and 25 g butter in a pan. Caramelise while stirring frequently until golden yellow. Quickly spread the caramel on the nuts with a tablespoon. Leave to dry for about 15 minutes. Chop the chocolate coating and melt with coconut oil over a warm water bath.
