World's Strangest National Dishes
Tacos de Sesos, Mexico
In a sly inversion of the old adage “The brain is a terrible thing to waste,” Mexicans are proud to serve up tacos de sesos. That’s cow brains—and, strictly speaking, they’re not unhealthy. But gray matter is very high in cholesterol—and according to the medical textbooks, bovine spongiform encephalopathy (a.k.a. mad cow disease) has an incubation period of up to 50 years. Brave this national dish at your own risk.
