When I first heard about this book I thought it would be a great read. I'm no expert at all as to what foods are kosher and really understand the basic tenants of it from school friends. But the title brought to mind of a story from the early 2000's where it was discovered that there were tiny organisms in the tap water causing a debate as to whether it was kosher and the move for people to install filters in their homes, restaurants to advertise they filter their water, etc. Or the stories of how Jewish people often go to Chinese restaurants on Christmas even though sometimes it might not be completely clear whether the restaurant's food is actually kosher, etc.
So I thought this book would be something like that and the author starts off by talking about his family and how he was driven to writing this book. Then the book quickly goes downhill from there.
Although there is generally some interesting information as to how Coca-Cola was kosher, how animals are slaughtered for kosher meat, etc. the book is dry, technical, academic, etc. It was best when he talked about his family but obviously that's not the focus of the book. I wanted to like it and did get some knowledge but it was a slog. Part of me wonders whether it's because I have a general lack of knowledge but I see from other reviews they also found the book pretty hard to get through.
If there's a specific topic of interest in the book it might be a good pickup. But I was disappointed to find the book wasn't what I thought it was nor was it very readable and I'm *very* glad I found it at my library. Otherwise I'd skip it.
