Cadbury's

Cadbury's was a brand of chocolate.

When Susan Foreman, John Brent and Gillian Roberts broke into the Coal Hill tuck shop in 1963, all they had was cold Cadbury's chocolate, Smith's crisps and Tizer. (PROSE: Time and Relative)

In 1966, the Ninth Doctor hastily made and consumed a sandwich consisting of a Cadbury's Dairy Milk, among other things, to neutralise his body chemistry after being poisoned by Charlotte Cobb. (COMIC: The Love Invasion)
