Leaf through your cookbooks, and you’re likely to find a bit of paper with a recipe written in a familiar (or not-so-familiar) hand. It could be a family secret finally divulged, a scribbled interpretation of something seen on TV, even a culinary experiment long since forgotten. What happens to these recipes when the books are passed on? By day, Michael Popek works in his family’s used bookstore. By night, he’s the voyeuristic force behind the websites ForgottenBookmarks and HandwrittenRecipes, where he shares the weird, wonderful objects he has found among the stacks at his store. Handwritten Recipes is a treasury of Michael’s most fascinating found recipes. You’ll find classic Americana like pies and casseroles alongside ethnic mainstays such as Italian cookies, springerle, and German dumplings. Some are perfectly clear and complete, while others leave crucial elements—like cooking times and ingredient measurements—to the reader’s imagination. You can venture to try any recipe, or just enjoy Popek’s findings as a time capsule from kitchens of generations gone by.
