As Ruth Wakefield was baking chocolate cookies for her guests only to run out of powdered baker’s chocolate, so she decided to break up a Nestle’s semi sweet chocolate bar. As some kitchen experiments do - it turned out into a semi-disappointment as the chocolate pieces only melted slightly retaining the shape. But the guests loved them and the next thing you know her recipe was up in a Boston newspaper increasing Nestle’s chocolate bar sales which then later granted Ruth a lifetime supply of the chocolate from Andrew Nestle as a reward for printing her recipe on the chocolate bars.
