Can rock candy be made in a plastic jar?

Here's why:

* Heat: The sugar syrup used to make rock candy is very hot, and plastic can melt or warp at high temperatures.

* Chemicals: Some plastics can leach chemicals into your food, especially when exposed to heat. This is harmful and will affect the taste of your candy.

* Cleaning: Sugar syrup can be very sticky and difficult to remove from plastic, making it hard to clean your jar.

Instead, use a glass jar or a heat-resistant container made specifically for food.

Remember, safety is always the priority!
