Snickerdoodle
A snickerdoodle is a type of cookie made with flour, fat, sugar, and salt, and rolled in cinnamon sugar. Eggs may also sometimes be used as an ingredient, with cream of tartar and baking soda added to leaven the dough. Snickerdoodles are characterized by a cracked surface and can be either crisp or soft depending on the ingredients used. Snickerdoodles are often referred to as "sugar cookies". However, traditional sugar cookies are often rolled in white sugar whereas snickerdoodles are rolled in a mixture of white sugar and cinnamon. Cream of tartar is added for its signature texture as another main difference. Joy of Cooking claims that snickerdoodles are probably German in origin, and that the name is a corruption of the German word Schneckennudel, a Palatine variety of Schnecken. It is also possible that the name is simply a nonsense word with no particular meaning, originating from a New England tradition of whimsical cookie names. The Oxford English Dictionary claims the word's origin is "uncertain", and possibly a portmanteau of the word snicker, an onomatopoeic English word with Scottish roots that indicates a "smothered laugh", and doodle, a German loanword into English meaning a "simple or foolish fellow", originally derived from the Low German dudeltopf, meaning "simpleton, noodle, night-cap". The earliest use of the word recorded by the Oxford English Dictionary is from 1889.
