Raoul is right. And George is right.
Don't judge U.S. burgers by McDs. Every city has more than a few good burger places.
Never having been Downunder (there) I thought George and LE were talking about putting slices of beets on their burgers. Which sounds deranged and dirty and disrespectful of The Hamburger.
But then.........
Finally, George described it thusly:
Picked young, boiled lightly in a spicy pickley vinegar
I NOW know exactly what he's talking about. And Raoul, I have a hunch you may, too.
I've had it at German restaurants here in China served with pork. Blue Marlin in Suzhou serves it with some of its dishes. The unwashed (like me, until now) thought it was like a purple sauerkraut, but sweetish not sour. I think that's the stuff George and LE are raging on about. I even bought a German brand jar of it once at the Metro and used it with Brauts. I thought of it as purple cole slaw (without the slaw dressing).
If that's the stuff, looks like fried onions in a vinegary, slightly sweet, purpilish, pickled concoction that can be spooned atop a burger patty ala grilled onions or cole slaw (without the slaw dressing).
I am so back to Metro to grab another jar. The stuff is really good alone or with pork or brauts. Gotta try it on a burger. I know it will be good! Also a good substitute for the lack of a good pickle here in China.
(Boss, I'm sure you had the stuff in Suzhou either at Blue Marlin or one of the other places there. Southern Cross surely has it as a side or garnish for some of its "continental" dishes.)
Now, about that phuqing fried egg on a hamburger thing...
