I think that first batch of onions would have been fine to use.
I find it difficult to caramalise onions that are finely processed (gone through kitchen machine of blender). I normally chop medium- coarse, then brown and then process.
I read somewhere that processing uncooked onions could turn them bitter, but I haven't really noticed that. Maybe another of those kitchen fables

By the way, good to see you again @koukouvagia

So:
Green onions
Blue garlic
Pink ginger (annecdote, years ago in Japan, I got ordered sashime and I thought that pink stuff was smoked salmon and I love smoked salmon. Put a big piece in my mouth and tasted pickled ginger)
