I hope this isn't my second post on this topic. For the past two years, I've noticed that onions touted as being sweet in my area (New England), aren't. I bought a couple of red onions (Sweet for Salads! the sign said), and they had an unpleasantly bitter/bite-y aftertaste...hard to describe. The same has happened when I've purchased even Vidalia onions, which I remember as being super sweet and mild to the point where I'd munch on chunks as if they were apple slices when I was a kid. What's up with this? Weather conditions? Is my palate changing? Has anyone else experience this?
Edited to add, I tried a quick pickling of the second red onion to mellow/change the flavor. I failed. Apart from a saute, is there anything I can do to help un-bitter an onion?
