Did you know?

The Celts believed that hazelnuts were a source of wisdom – the Gaelic word for the nuts was cno, with the word for wisdom being cnocach. They had an ancient tale of nine hazel trees that grew around a sacred pool. Salmon living in the pool ate the falling nuts and absorbed the wisdom. The number of bright spots on the salmon’s skin showed how many nuts they had eaten.
