What is "rock candy"?

Rock candy is a type of candy that is made by crystallizing sugar. The process involves dissolving sugar in hot water to create a concentrated sugar solution, which is then left to cool and form crystals. The crystals grow over time as the water evaporates, resulting in a hard, crystalline candy that is often sold on a stick. Rock candy can be flavored with a variety of ingredients, such as fruit extracts or essential oils, and can be colored with food coloring. It is a popular treat for both children and adults and is often used as a decorative element in desserts and beverages. Additionally, rock candy has a long shelf life, making it a great choice for gift giving or as a sweet treat to have on hand.
