Handwritten Recipes is a wonderful blog devoted to recipes discovered between the pages of unrelated books. Now, blogger Michael Popek has collected his finds in a book that manages to combine social history, literary history, and, yes, recipes. Each image is a story: Did the quotidian demands of dinner intrude on Catch-22, or was the reader’s mind wandering? Did a neighbor drop by with a recipe? Was it solicited, or forced on the cook and consigned to bookmark status? The world may never know, but it’s fun to speculate. Below, just a few favorites.
