When making rock candy, the choice of stick is an important decision. The stick acts as the handle and base for the sugar crystals to form on. The best sticks are ones that are sturdy, non-toxic, and allow the sugar solution to spread evenly across the surface. Here are some of the most popular options for rock candy sticks and the pros and cons of each.
Wooden Sticks
Wooden sticks like popsicle sticks or chopsticks are a classic choice for rock candy. They are inexpensive, easy to find, and provide a smooth, non-porous surface for even crystal growth. Look for wooden sticks that are a bit sturdier than regular popsicle sticks to support the weight of the crystals. Avoid splintery or very thin sticks. Make sure to get non-treated, non-varnished wooden sticks to avoid toxins leaching into the candy.
Pros:
- Inexpensive and readily available
- Provide an even, non-porous surface for crystal growth
- Sturdy enough to hold heavy sugar crystals
Cons:
- Can be a bit thin and flimsy if regular popsicle sticks are used
- Need to be mindful of non-varnished, non-treated wood
Plastic Sticks
Plastic sticks like lollipop sticks, straws, coffee stirrers, and plastic spoons work well too. Make sure they are thick enough to support the weight of the crystals. Plastic sticks should be food-safe and free of any odors or toxins. Clear plastic sticks allow you to observe the crystal growth.
Pros:
- Very inexpensive
- Sturdy enough to hold heavy crystals
- Food-safe and odor free plastics allow for clean candy making
- Clear plastic sticks let you watch crystals grow
Cons:
- Can have a plastic aftertaste if low quality plastic is used
- Cheap plastic may crack under heavy crystallization
Metal Stirrers
Copper, gold, and silver candy molds and stirrers can be used for elegant, expensive-looking rock candy sticks. These metal sticks provide an excellent base for crystal growth and conduct heat well for crystal manipulation. Make sure to get food-grade metals to avoid contamination.
Pros:
- Elegant, luxury presentation
- Excellent for crystal manipulation with heat conduction
- Sturdy for heavy crystallization
Cons:
- Expensive compared to wood or plastic sticks
- Metal can react with acidic foods like citrus rock candy
Wax Paper
Wax paper strips can be used as disposable rock candy sticks. The wax provides enough stability for crystals to grow on both sides while still being bendable. These work well for rock candy that will be crushed or used for cooking/baking. The paper strips are compostable.
Pros:
- Inexpensive and disposable
- Allows crystallization on both sides
- Compostable and environmentally friendly
Cons:
- Not as sturdy as reusable sticks
- Can’t support heavy crystallization
- Hard to handle once sticky with crystallized sugar
String
Cotton string, twine, or thin rope can be used as the base of rock candy. String provides more surface area for crystal growth. Make sure to use unflavored, untreated cooking string only. The texture of the string may affect crystal shape.
Pros:
- Interesting crystal shapes due to string texture
- Provides lots of surface area for crystallization
- Inexpensive and reusable
Cons:
- Crystals may be fragile and break off string easily
- Natural fibers can develop mold if not dried properly
- Not as easy to handle sticky string
Edible Sticks
Edible items like pretzel rods, licorice, twigs or cinnamon sticks can provide a tasty stick base. Choose hard, dry items that won’t get soggy in the sugar solution. Food oils may inhibit crystallization so thoroughly wash and dry edible sticks first.
Pros:
- Fun presentation and added flavor
- No special tools needed – just food!
Cons:
- May dissolve, crack or become soggy
- Oils can inhibit crystallization
- Less sturdy than reusable sticks
Conclusion
Wooden sticks, plastic sticks, and paper strips tend to be the most popular options for rock candy. Look for thick, sturdy sticks that are food safe and heat tolerant. Avoid splintering wood, cheap plastics with odors, and natural fibers that can grow mold. While metal and edible sticks add flair, they can be less ideal for crystal manipulation and growth. Choose sticks that are reusable and environmentally friendly. With the right sticks and a little patience, you’ll be rewarded with gorgeous homemade rock candy!
