Yummmm. Girl Scout cookies. This yearly treat is a favorite among many. And everyone has an opinion about which one is the best.
Girl Scout cookies have been around since 1917. So if your grandma or great-grandma was a girl scout, chances are she helped sell these delicious treats. When the idea started, the girls baked the cookies at their house and then sold them. an early cookie recipe can be found at http://www.girlscouts.org/program/gs_cookies/cookie_history/early_years.asp. This site also provides a history of the cookies from their beginning through the decades. During the World War II years when there was rationing and shortages, the Girl Scouts had to sell calenders instead of cookies. Another history of the cookies, including a picture of two girls baking those early creations can be found at http://www.pabook.libraries.psu.edu/palitmap/GirlScoutCookies.html.
