Ruth named her happy accident "Toll House Crunch Cookies." News of her new cookie invention spread quickly and her "Crunch Cookies" became a huge success around town. The recipe ran in a Boston newspaper, popularity increased and Nestle's semi-sweet chocolate sales rose. Eventually, Nestle approached Ruth with a proposition: in exchange for a lifetime supply of Nestle's chocolate, Ruth would permit Nestle to print her recipe on the back of their chocolate packages. Nestle also bought the rights to the Toll House name, and at Ruth's suggestion, score their chocolate bars so that they would be easier to break into small pieces. Soon they began to sell chocolate chips and chunks, making it even easier for the chocolate chip cookie maker. And to think that all of this came from want of baker's chocolate and a little ingenuity.
