Frequently Asked Questions
No. British 'rock' (like Brighton rock) is a hard, cylindrical candy with writing through it, often flavoured with peppermint. American 'rock candy' is clear, crystalline sugar on a stick or in chunks.
Yes, but rarely and informally, meaning 'to form into crystals like rock candy' (e.g., 'The sugar rock candied on the string').
It is made from refined sugar, so it is a processed food, but the crystallisation process is a physical one, not involving complex chemistry.
The term 'rock candy' is American-centric. In the UK, it's more often called 'sugar candy', 'crystal candy', or simply referred to descriptively. 'Rock sugar' is a related culinary ingredient.
