Line a baking sheet with parchment paper or a silicone mat.
Make your fortunes either by writing them or on the computer. They should measure about 6cm x 1cm.
Beat the egg whites, orange-blossom water and oils together in a bowl until frothy.
Sift the flour, cornflour, salt and sugar into another bowl. Add the water to this mixture. Then add the egg mixture to the batter, stirring until smooth.
Bake these in 3 batches of 5 or 6 at a time. Place tablespoons of the batter on to the prepared baking sheet. Use the back of a metal spoon to swirl out the mixture into 10cm circles. Leave space between each as they will spread a little during cooking.
Bake for 10-12 minutes until light golden brown, then remove from the oven with a spatula. Place a rolled up fortune in the centre of each one. Do this quickly while the cookie is still soft and pliable. Fold it in half and pinch the edges together to seal. Place the folded edge of the cookie over the rim of a cup and gently pull the 2 corners down to form the classic fortune cookie shape. Transfer to a wire rack to cool.
If the cookies have softened by the time you come to serve them, crisp them up in the oven for a few minutes.
