What food smell do you hate?
Inspired by the thread: What's your favortite food smell?
This time around, what food smells do you dislike or hate? I'm not talking about things that are inherently bad, like rotten eggs or something else equally putrid. Just normal scents of foods that make you gag or are unpleasant to be around.
For me, it's the smell of bacon. I don't love it, but I'll eat it if it's in something. I just hate how the smell permeates everything when it's cooking.
