@Zfug I didn't rated it 1 star but I understand why some people can rate it so.
The world building is dumb, nobody in their right mind would "cook" like the elves, by trial and error, or even by sheer luck, the dishes would not be the same and would improve little by little.
Or in the slight chance they would always cook like that it'd shape their taste and they'd dislike other type of food that are too much different. (and if they didn't improve volontarily it's because they prefer it that way).
Then the all "off with their head" is dumb too, killing someone over a small mistake without chance of redemption is nonsensical.
If the cooking was so revered, it'll not be given to a random person but by a pretress or someone with high status which would not just give their right to cook to a stranger easily (even more if they know they risk to die if they makes a small mistake).
The two major things that drive the plot and around which the world is build are entirely flawed. Which just ruin it.
The cooking part is so-so, and reaction of the food is kind of meh.
The elves' characters are bland.
So yeah, not a good manga.
