Rock candy has been a favorite in American households for decades. Its crystal-like form, sweet flavor, and simple ingredients make it both nostalgic and fun. Whether used as a treat, decoration, or even a science project, rock candy holds its place among timeless sweets.

With roots dating back centuries, rock candy is more than just sugar on a stick. It has cultural significance, health-related uses, and even economic value. Let’s explore everything about this glittering sugar crystal.

What Is Rock Candy?

• Popular in the U.S., especially for parties and holidays

It’s typically served on sticks or strings and comes in various colors and flavors.

In the United States, rock candy gained fame during the Great Depression due to its low cost and long shelf life.

How Is Rock Candy Made?

The process is simple but requires patience.

1. Boil sugar and water until the sugar dissolves.

2. Add food coloring or flavoring if desired.

3. Pour the solution into a jar with a stick or string suspended in the middle.
