The Fort Negen recipe book is the ultimate baking guide for anyone who not only wants to follow recipes but also understand the science behind the dough. With over 150 recipes and variations—from sourdough bread and croissants to cruffins, pastries, sandwiches, and fermented goods—you’ll gain a unique insight into the world of one of Amsterdam’s most beloved bakeries. These are the authentic Fort Negen recipes, exactly as they’re used in the bakery, just scaled down for home baking.

The recipes are immediately practical, with techniques explained clearly and step by step. For those seeking more than just baking instructions, the book offers real depth: you’ll not only learn how to make each recipe, but also why it works. From the foundations of grains and fermentation to the (micro)biological and chemical processes that bring dough to life—everything is presented in an accessible and easy-to-understand way. This knowledge empowers you to understand, experiment, and refine your baking skills and intuition.

The book will be released on September 9th and is available for pre-order now!

On September 10, we're hosting the book launch at the bakery. Drop by from 8 AM and you’ll receive a free sample of our dried sourdough starter to kick off your sourdough journey.

This book is the result of years of experience and study by Maarten Langeslag, who learned from bakers and experts around the world, as well as from books and scientific literature. His journey from home baker to founder of Fort Negen is distilled into a book designed for both passionate home bakers and professionals. It’s also supported by video content, allowing you not only to learn the techniques but to see them in action.

In addition, you'll discover how to creatively upcycle leftovers into new creations and how to refine flavor combinations. This book teaches you not just how to bake—but why—helping you elevate your baking instinct to a whole new level.
