Behind the Recipe
This recipe grew out of memories of watching bright red candy cool on my grandmother’s counter every December.

Now, making it feels like reliving those moments, bringing that childhood joy back into the kitchen one piece at a time.
Recipe Origin or Trivia
Rock candy has been crafted for centuries in cultures around the world. It began as large crystallized sugar formed on strings, but later evolved into flavored hard candies as sugar became more accessible. Cinnamon versions became especially popular in the United States during the mid 1900s when bold red sweets became a holiday staple. This recipe keeps that classic tradition alive.
