Which British seaside town was the first to have its name written through a traditional stick of rock?

Rock is a type of hard stick-shaped boiled sugar confectionery most usually flavoured with peppermint or spearmint. It is commonly sold at seaside resorts in the United Kingdom. Rock was first made by a young man named Ben Bullock whilst holidaying in Blackpool. He began producing sticks of brightly coloured, lettered candy sticks at his Yorkshire-based sweet factory in 1887. He sent his first batch of lettered rock to retailers in Blackpool, where it had ‘Blackpool Rock’ running through the centre.

A stick of rock is usually 1–2.5 cm (0.39–0.98 in) in diameter and 20–25 cm (7.9–9.8 in) long. These cylindrical shaped confectionary normally have a pattern embedded throughout the length, which is often the name of the resort where the rock is sold. Letters are formed by combining thin strips of multi-coloured and white toffee.

Blackpool is a seaside town in Lancashire, in the north west of England. Blackpool became important for tourism during the 19th century. It is known for its beaches and amusement parks. It is also the home to a famous international ballroom dancing competition.
