I eat practically everything. But there are limits.
1. Cotton candy
Sticky, sugary, disgusting
2. Homemade sauerkraut (made by some people)
The stench of sauerkraut, if not done well, makes me gag instantly
3. I remember the account of an explorer who visited a tribe in the Amazon
There is a root that is considered a special delicacy. It is chewed up by the women and spat into a pot. This porridge ferments. It's considered very rude for a visitor to refuse to try it.
