After giving this considerable thought over the past 10 years, I have concluded that the nastiest food on this planet (barring bizarre concoctions), is irrefutably:
Watered Down Ketchup
Imagining drinking a big glass of it on a hot summer’s day, and tell me I’m not right.
How about mayonnaise in which the oil has gone rancid? I’d drink watered-down ketchup over that anyday!
Nato is pretty nasty.
It’s rotting beans, which, according to my SIL don’t taste good, smell good, or have a pleasant texture - and she LIKES it.
I have no explanation other than she also seems to dig chicken ovaries, so I suppose there’s no accounting for taste.
Without the slightest shadow of a doubt, ANDOUILLETTE SAUSAGE. It’s the intestines of a pig (I think) stuffed into a skin which is itself made out of the intestine of a pig. I believe it’s the custom in France not to wash the intestines before use; at least that’s what seemed to be the case with the one I encountered in Bordeaux a few years ago.
It tasted like (excuse me) shit. Not that I have ever eaten shit. Except probably on that occasion.
Herring in sour cream sauce. :eek:
I see it in the kosher isle of my grocery store and I always wonder how starved I’d have to be to actually be able to make myself choke it down.
Anchovies are just as loathsome.
Finally, those crusted balls of shrink wrapped congealed animal fat and grease in the meat section (spetzle? scrapple?). Bleh!
Cottage cheese.
Just thinking about eating it makes me feel like crying.
Liver with brussel sprouts.
When my former MIL would cook that, I’d drop off my wife. FIL and I went to the corner bar, had sammitches and shot pool.
Herring in tomato sauce :eek: Maybe herring in watered down tomato sauce?
Raw herring
Any herring
in fact: Any fish.
[or liver]
Sauerkraut.
ducks the kraut lovers
Kraut juice? Come on, you gotta admit kraut juice…
If you were feeling stingy you could add more water to the recipie, and have watered-down Kraut Juice Delight…
I can’t believe I’m the first person to say Haggis.
hehehehe 
I just had sauerkraut soup. Yummy.
HAGGIS - lamb’s liver, oatmeal, suet, and onions boiled in a sheep’s stomach bag.
Served with kraut and watered down ketchup. 
Damn. Must type faster!
I’ll see your haggis and raise you deep-fried haggis.
Those Scots will deep-fry anything. The pizza and candy-bars didn’t freak me out so much, but… the haggis… :eek:
Any organ meat.
Feta cheese. The smell alone could kill a herd of raging rhinos.
Ditto cottage cheese.
Oh yeah, tripe.
And not the last. It’s the only so-called food that I had to literally force myself to swallow (and keep down) one piece.
Then I tried vegetarian haggis. I don’t know how, but they made it taste just as bad as the real stuff.
And then there’s Limburger cheese.
I don’t know what you mean, but spaetzle are delicious pillowy nuggets of noodly goodness, and I would hate to see their name inadvertently sullied.
Mine is: fish sauce. I can eat things that contain fish sauce, but only if you cannot taste the fish sauce.
Ick.
Fish sauce.
Fried squash.
Hace you Haggis haters actually tried Haggis, it is yummy-nice. Specially with neeps and tatties.
