Are you asking why Everton is called Toffees? The origin of toffee is as follows:

Everton has a well-known toffee candy shop, Norblett Mama, which specializes in various desserts, and the store location is opposite the one in the Everton team logo. At Prince Rupert Tower, it became a tradition for the club that the girl selling toffees would go around the pitch and throw free Everton mints into the stands before the game started, hence the name Everton.

Another view is that a toffee workshop run by Mrs. Bushell became the real source of the nickname due to its proximity to the Queen's Head Hotel, where meetings were often held in the early days of the club.
