Cut the vanilla pod lengthwise and scrape out the pulp. Finely chop macadamia nuts and mango separately. Beat egg white with vanilla pulp, sugar and icing sugar until very stiff (approx. 8 minutes). Mix starch, grated coconut, macadamia and 20 g mango pieces and carefully fold into the egg whisk mixture. Pour the mixture into a piping bag with a perforated spout (11 mm Ø) and squirt elongated tongues (approx. 6 cm long) onto 2 baking trays lined with baking paper.
Sprinkle with remaining mango pieces. Bake one after the other in a preheated oven (electric cooker: 150 °C/ convection oven: 125 °C/ gas: level 1) for 10-15 minutes until slightly browned. Take them out and let them cool down. Chop the chocolate coating and melt over a warm water bath. Pour the couverture into a piping bag and decorate the macron tongues with wavy lines
