1. Shirako, Japan

Considering the popularity of caviar—not just in Japan, but worldwide—it’s not outlandish to imagine eating the male counterpart to fish roe. That is, milt—the sperm-filled reproductive glands of male fish (usually cod, anglerfish, or puffer fish). In Japan, it’s called shirako, which translates to “white children.” At best, when cooked, shirako has a creamy, custardesque texture. At worst, it’s an unctuous gooey blob served raw—and eaten proudly by only the most, er, seminal of Japanese diners.
