Fortune cookies are uniquely-shaped, crisp cookies made from a simple recipe of flour, sugar, oil and either vanilla or almond flavoring. They are called fortune cookies, because each cookie breaks open to reveal a small slip of paper â a â fortune  â with a prediction for the future, a wise saying, a Chinese word or phrase with its translation, or even a list of lucky numbers.
When 97% of the caffeine has been removed only (1.36% / 97% =) 0.0408% of the coffee caffeine by weight. About 4/100ths of 1%. At this level it is labeled âdecaffeinatedâ. How roasters label their products is another matter.
Decaffeination is not very efficient, so decaffeinated coffee and tea often contain a lot of caffeine. The amount of caffeine left can vary widely, and there is no way to know how much caffeine you're getting, even if you always go to the same place to get your drink.
