A humbug sweet is traditionally flavoured with what?

Humbugs are usually flavoured with peppermint and striped in two different colours (often black and white). They are a traditional hard boiled sweet available in the United Kingdom, Ireland, South Africa, Canada, Australia, and New Zealand. In Australia, the black and white striped humbugs are flavoured with aniseed instead of peppermint.

Humbugs may be cylindrical in shape with rounded ends wrapped in a twist of cellophane, or more traditionally tetrahedral formed from pinched cylinders with a 90-degree turn between one end and the other (shaped like a pyramid with rounded edges) loose in a bag. Records of humbugs exist from as early as the 1820s, and they are referred to in the 1863 book 'Sylvia's Lovers' (a novel written by Elizabeth Gaskell) as being a food from the North of England.
