To start, combine the dry ingredients, thus shredded coconut and sugar.
Then add egg whites and mix evenly. The aspect remains quite dry, that’s normal.
Place a sheet of baking paper or parchment paper on a baking tray. Using a spoon, make small heaps of the shape of a rock (it won’t change while baking) of the size of your choice. Make sure that they are all the same size so that they will cook evenly.
Lower the oven to 200°C (400°C) and bake for about 10 minutes. It is difficult to give a precise baking time because it all depends on the size of your cookies. As an indication I baked 10 min at 200 °C for the 22 cookies I made with the indicated quantities. Be sure the remain a bit soft thus chewy in the inside..
