One of my favorite foods is natto. It's stringy. It's fermented.
They say it's an acquired taste, but in my opinion you either like it or you don't. Natto is made from soybeans fermented with bacillus subtilis. The Japanese like to eat natto for breakfast on top of rice. No Special K or Cheerios for them; their mornings start with a rich diet of healthy protein. I like to eat my natto with a fried egg, soy sauce, and grits. An East meets West recipe. This is what I had for breakfast today...yummy!
Natto can be purchased in an Asian grocery store here in the States. It comes in a cute packaging that has soy sauce and mustard that is stirred into the natto before eating.
