Put the coconut on a parchment paper covered baking tray, spread it evenly. Bake for 10 minutes, stirring regularly, until the coconut is golden and toasted. Set aside to cool.
In a bowl, mix the flour, sugar, nutmeg, baking soda, salt and coconut. Add water, 1 tbsp at a time and mix with your hands, the dough must hold together.
Shape it into a rectangle and wrap it in cling film. Refrigerate for 15 minutes to harden.
