Are you the guardian of a heritage snickerdoodle recipe? Or perhaps you’re the culinary creative behind a melt-in-your-mouth chocolate chip cookie? Sweet Tooth author Sarah Fennel, who runs the blog Broma Bakery, wants you to share your secrets – or at least, how great they taste. Fennel welcomes cookie recipes from every grease-stained cookbook and muscle-memory-worn technique at her booksigning and cookie swap. Bring your sweet tooth and a dozen or two treats to share for an evening of taste testing, recipe swapping, and lots of crumbs. You just might leave with some new tricks up your flour-coated sleeve. – Caroline Drew
