Ugh, another story that makes everyone so incompetent that the MC looks skilled by comparison.
I mean seriously, you have people in chef outfits that are assigned to a high ranking aristocrat, straight up cutting their own fingers while trying to chop vegetables... Seriously, WTF?
There's also so many basic problems with the story, for example how is dried meat a high ranking/precious ingredient? In a world overrun with monsters? Where meat has to be the most overabundant food resource?
Or how is it that people seem to be both aware of the fact that their food tastes like shit, but at the same time no one cares about improving it? Are they not human? I mean, the history of earth is full of people who would willingly add known toxic materials just to make food taste a little bit better...
