I really like cooked onions but I dislike raw onions. If the onion is raw, I taste it almost immediately and might remove it. My favourite onions are the ones that are caramelised.
grilled onions offer so much flavor! sweetness, savoriness if you slightly salt them, a great allium sharpness without the spiciness of a raw onion. excellent additions to a burger!
a well-soaked and drained raw onion comes in handy too! crunchy texture, same onion-y flavor, slightly more spiciness.
i'd go for caramelised onions! though grilled onions are good too. raw onions make me cry and i try to avoid the mega warmth when i'm doing a consume of foodstuffs. and an avoid of people the day after lmao
if it's grilled or cooked, and if it's in tiny slivers or the smallest of slices, i can tolerate onions on my burger. but if it's raw or has a bunch of onions on it, i just take them off and go about my meal. i don't really like onions but don't mind them if they're cooked and i can't notice them
I have severe sensory issues with onions that I haven't been able to overcome. My brain can apparently detect even the tiniest of little pieces and promptly tell me to spit it out.
So none. But onion powder in my burger? Sure, go for it. It's the texture I hate, not the taste.
