Years ago, I read a book called The United States of Arugula that detailed the history of food availability in the US from about the 70s to the 2000s and how we enjoy so much more variety at the average grocery store now, even in small towns. And it’s true!
Celery root is one of those things that I didn’t eat until I was an adult. I don’t even recall seeing it in the stores until I was older, and most of that is likely from growing up in a really small town. The point is, here’s this gnarly looking “vegetable of the underworld” that is quite tasty and who knew? Not me until possibly cooking through Dorie Greenspan’s book ~9 years ago.
