What’s the first thing that comes to mind when you think of caviar? “Oh, what a delicacy!” or “Ew! Fish eggs.” Whether you’re a fan or foe, National Caviar Day is celebrated nationwide on July 18 every year. Technically, real caviar isn’t just any fish eggs. It comes from the the female sturgeon fish. And it’s been a high-end dining staple ever since Cesar Ritz (fancy hotelier) put it on his menus.
