I tried some pickled onions from an Idian place near me and while I generally hate onions in all forms (except onion powder or onion flavored chips for some reason) I didnt realize how different they could taste when made in proper ways. I was literally eating them on their own by the spoonful because they were so good, never in my life did I expect that to ever happen. So while its prevelant in Indian dishes, it just feels like they know how to actually use them versus some plain disgusting raw onion chopped and added to like a salad or burger. Like anything there is always nuance, and that day I learned it ever applied to the eating onions lol
