The cookie is interpreted in the United States and Canada as a small, flat, custard-style cookie. Its name is derived from the German word koekje, which means "small custard". The word is mainly used in British English to distinguish American cookies such as "chocolate chip cookies". The first cookies were made by combining several small slices of omelette. It is believed to have been invented by the Iranians.

Making

Different kinds of cookies have different softness. Some cookies are not even fully cooked through. Cookies come in many different styles such as sugar flavored, spice flavored, chocolate flavored, butter flavored, peanut butter flavored, walnut flavored or dried fruit flavored.

The way cookies are made can be roughly summarized in the following theory. Although different cookies have different characteristics, they are cooked in a similar way, using a large amount of water as a cohesive force. This water is used to make the base as thin as possible (in this case called "batter") and to allow bubbles to appear. And after that, a large amount of butter and eggs are added, which, because of their high oil content, allow the cookies to finish cooking in the microwave.

The baked eggs don't have much water in them. Instead of evaporating and thickening the mixture, it is left behind to saturate the bubbles and escape from the small amount of water in the egg, while carbon dioxide is released by the heat. This saturation process creates the cookie's most appealing characteristic, which is its crisp texture.

* refrigerator cookies, in which the drier cookie batter is rolled into sticks and chilled in the refrigerator before being formed into cookies;

* filled cookies, in which the cookie batter is kneaded by hand into balls and then wrapped in a jam filling.

* filled cookies, which are hand-rolled balls of cookie batter with a jam filling.
