I'm instantly distasteful of any recipe that adds onion for flavour. That stuff is pervasive, overpowering, and in nearly everything already. Unless onion is the focus of the recipe, I'd like to actually taste the food in the dish, not onion again.
Drag can't taste onion. It just takes like stringy nothing. Like a slightly more robust grass. It's annoying to eat because it gets in the way of the flavour.
Bro you need to get some chiles and spices into your life. Also not for everyone but cooking fish definitely has an aroma and I'm going to assume you like fish if you're cooking it.
