I recently bought a a jar of rock candies and after one night, they have melted and all stuck together. How do I separate them again to eat them? (I tried freezing, it didn’t work!)
If you can get them out of the jar, I would suggest a hammer.
Put them in a plastic bag and whack them with the hammer.
You might be able to use a knife (carefully) to pry them apart depending on much they are stuck together.
You can try filling jar with water (warm water is more effective) so they start dissolving and unstuck. Then they can be dried outside of the jar.
