Bridget Heaney is a young Irish girl trying to find her way, like so many others in 1860s New York. Her first break is working in the kitchen for one of New York's most prominent men--Isaac Gold. There, hidden high on a shelf, Bridget finds an old wooden spice box, carved with scenes and filled with recipes--with different handwriting and in different languages: the legacy of generations of cooks, handed down through the years.
