Who was first to make rock candy?

It's impossible to pinpoint exactly who first made rock candy, as it's a process that likely developed over time and across different cultures.

Here's what we know:

* Ancient Origins: Sugar crystallization techniques, the foundation for rock candy, existed in ancient civilizations like Persia and India. They knew how to boil sugar syrups to make sweets and even crystallize them, but these techniques were likely more rudimentary than what we now call rock candy.

* Medieval Times: The process of making rock candy, as we know it, probably emerged in Europe during the Middle Ages, when sugar became more accessible and refining techniques improved.

* No Single Inventor: There is no specific person or event recorded as the "first" to make rock candy.

So, while we can't definitively say who invented rock candy, it's safe to say that the process developed gradually over centuries, building upon techniques from different cultures.
