Your comment got me curious and so I went to look it up. Apparently we've had granulated sugar for over 2000 years: 1700s CE Europe liked to import it. The process was with sugar cane, but I don't imagine it's be all that difficult for people to think up of a mill for it, when they already have flour mills.

It’s not that I think they lack the skills to make it- rather they lack the need to possess it. Food there is so bad.
I mean 2000 years ago Rome/ancient Greece had fabulous food. Go to a Greek food festival some time. But this world has sh*t food. Why do they even HAVE granular sugar? I just can’t imagine them actually using it.

That's fair LOL. But back in the day; when spices first started to make their way via import, just having them was sort of seen as a luxury item (sugar over salt especially); so I would imagine some people just have it as a status symbol, even if they're not sure how to fully utilize it. --- But other than food; it can be used straight in drinks or teas.

Loll honestly reading this now reminds me I have to turn off my brain cause of how they push so hard for the "look at us! we're so advanced compared to the place we isekai-ed to". Parallels how modernly we tend to portray people in the past is dumb, when actually they were also smart. Just didn't have the same tools and resources that we now take for granted.
Like you can't convince me that there wasn't someone who was like fuck this shit, let's makes this taste better. Hell, a gin and tonic literally came from this exact mentality cause quinone which prevents malaria is so god awful tasting
A little surprised that a world where the food culture is so poor it requires saving would have ingredients as complex as granular sugar…
