Slimy foodstuffs we know and love. Aside from okra,
→[More:]most of the slimy foodstuffs I know are Japanese: natto and yamaimo (mountain potato) come to mind. Yamaimo has the added benefit of giving you a rash if it touches outside of your mouth.
I like these things, but understand how they could be hated. Any other slimy foodstuffs out there worth trying? Any other food items that cause rashes or other discomfort (and I don't mean hot peppers the day after)?
