I've seen headcanons about Cardassians eating spicy food but learned recently from watching videos about peppers by the guy who bred Pepper X and Carolina Reaper that apparently only mammals react to capsaicin by perceiving it as "heat," it doesn't affect other animals that way, so actually that would make it even funnier - if Cardassians are reptilian enough they can't even process spicy foods so they're eating these mega spicy peppers and it's just whatever, and then like, Garak makes some food with it for his dear doctor and Julian is like what the FUCK did you put in here, get me some water NOW (funnier: Dukat also tries to do this to Sisko at some point for Reasons but Sisko's years of experience with Cajun cooking give him a much higher tolerance)
