Imagining a fantasy setting where elves, dwarves, orcs and whatnot are just continually baffled by humans eating the most vile toxic things.
Salsa? You mean a mix of a hemolytic poison (onions), a cardiotoxin (tomatoes), and a nerve agent (chili peppers)? Eaten with corn chips dusted with a lethal amount of salt, and washed down with a cup full of neurotoxin (iced tea)?
Stay the fuck away from me because clearly you are the vile spawn of some incomprehensible eldritch god
In D&D dwarves have resistance to poison damage and advantage on saving throws against poison, so they would be the ones with food no one else could eat safely.
To everyone else, dwarf food seems bland. Since the dwarf cooking it couldn’t add any of there normal spices. “Can humans eat rocks? I don’t think so, better skip them.” (Then skips the salt)
Fun fact; you shouldn’t swallow pebbles. You can digest them, but they are rich in toxic minerals, to the point that your kidney gets overwhelmed.
I’m so glad I learned that I could digest rocks as an adult. I don’t think the second part of that warning would have been enough to deter me as a kid.
