Mmmmm… Interesting. I do actually like raw onion; onion in any state from straight out of the ground through to "how more cooked could this be?!" Onion marmalade, mmmmmmmm….

But, I grant you, whilst sweet onion is an oxymoron frankly, you don't want too pungent an onion if you're eating it raw. It's always a bit hit & miss (& the sulphur increases with age, which is the "Arrrgh!" part of proceedings), but every lunchtime work salad I've ever made included a chopped raw onion...
