 They used the first syllable of each of their surnames to come up with the name Bendicks.In 1931 Benson's sister-in-law, Lucia Benson, came up with a dark chocolate so bitter that it was virtually inedible on its own, and combined it with a mint fondant that was so strongly flavoured with mint oil that it was also difficult to eat on its own.When the two parts were combined they produced a very palatable chocolate that they named Bendicks Bittermints.
