What does fortune cookie do?

The oven is preheated to 200 degrees Celsius. Spread more butter on two baking pans. Write the words of fortune-telling on a piece of paper with a length of 10 cm and a width of 1.25 cm.

Stir the egg whites and vanilla extract until foamy but not thick. Sieve the flour, salt and sugar with a fine sieve and mix well.

Scoop a spoonful of batter onto the prepared baking tray with a distance of at least 10 cm. Tilt the baking tray left and right to make the batter flow into a circle with a diameter of about 7.5 cm, and carefully make the batter as round and flat as possible. Don't make too much at a time, because the cake can only be folded when it is very hot, and once it is cold, it will be too late. Try to make 2-3 pieces at a time on the baking tray and see how many pieces you can make.

Bake for 5 minutes or until the outer edge of the cake is 1.3 cm wide and the center is still gray. While baking one plate, prepare the next one.

After taking the cake out of the oven, quickly use a spatula to reverse the cake on the wooden chopping board, quickly put the written divination note near the center of the cake, and then fold the cake in half. The folded side straddles the edge of the measuring cup, and then the tip is pulled down, one inside the cup and the other outside the cup. Finally, put the folded cake into a small paper cup filled with muffins or a small paper box filled with eggs to set it hard.
