What is the worse thing you've ever eaten ?

Sour Kraut Soup. My friend swears by the stuff so I tried to make it. I seriously think I did something wrong because it was so gross. My husband came home and wouldn't even try it because the house smelled so bad. We both love sour kraut. I told my friend that next time I come home I want her to make some so I can see what it should look, taste, and smell like. So gross.
