AITA for not letting my sister's boyfriend use hot sauce?

Every Sunday my family rotates who makes dinner. One day it's my wife and I, the next time is my sister and her boyfriend, the next my mom and dad, and then finally my grandmother. With our busy lives, this day is important to us because besides holidays, we wouldn't be able to meet up and chat or eat without it.

We come from an Italian family but are in Canada (my mom was born there, I was here). I take my food very seriously, especially Italian food, and double especially because my nonna is eating with us.

I spent all day preparing dinner and when we sat down to eat, my sister's boyfriend is humming and hawing saying my meal is missing something. He said he needs hot sauce and starts walking to my fridge. All I have is Franks and Sriracha. I like hot sauce, too, but I don't dare mix cuisines like that.

So I stopped him saying I'd appreciate if he enjoyed my meal as it is. He said it's no big deal, and in a way it isn't, but also in many ways it is. I told him at the very least, I have some Calabrian chili oil he can use, or dried chili flakes. Then it would at least still be Italian. He insists on Sriracha, and I declined him.

He escalated it and said he was going to go to the store and buy his own bottle and return if that's the case, and I said by all means. He left, we finished up dinner, and we called it an early night. Everyone is putting their coat and shoes on as he returns, and he's pissed.

Was I TA? My sister is on my side if it matters, but this has been a fight all day yesterday between them because he wants my sister on his side, not mine. They've been dating only 3 months.

edit: if it matters, I made carbonara, bruschetta, and then for mains which he didn't get to yet, was a seafood platter in red sauce. My wife and I are 34, 35 respectively, my sister and boyfriend are 23, 22 respectively.
