Some prefer the indulgence of delicious fresh baked goods,like chocolate chip cookies.These people should be grateful for an accidental discovery made by an American housewife and inn owner in 1930. One day Ruth Wakefield was making chocolate cookies when she realized that she had run out of baker's chocolate.Wakefield decided to subsitute broken-up pieces of a chocolate bar she had on hand.She assumed that the small pieces of chocolate would melt and max into the batter.
