Prepare your fortunes by writing the pithiest of phrases you can think of on pieces of paper that are 3 1/2 inches long by 1/2 inch wide.
Preheat oven to 300F. Grease 2 baking sheets.
In a medium bowl, lightly beat the egg white, vanilla extract, almond extract, and vegetable oil until frothy but not stiff.
Sift the flour, cornstarch, salt, and sugar in a separate bowl.
Stir the water into the flour mixture.
Add the flour mixture to the egg white mixture and stir until you have a smooth batter. The cookie batter should not be runny, but should drop easily off a wooden spoon.
Use a medium cookie scoop to pour six portions of cookie batter onto each cookie sheet, spacing them at least 3 inches apart. Gently tilt the baking sheet back and forth and from side to side so that the batter forms a cookie that is roughly 4 inches in diameter.
Bake unil the outer edges are golden brown, roughly 14-15 minutes. While the cookies bake, prepare your shaping implements: a flat spatula, a wooden spoon, and a 12-cup muffin tin.
Working quickly, remove the cookie with a spatula and flip it into your hand. Place a fortune in the middle of your hand and put a fortune in the middle. Fold the cookie in half, then gently pull the edges downward around a wooden spoon or the edge of the cup. Place each formed cookie in the cup of the muffin tin to fully cool.
