The Rescue chapter is organized around problems you can recognize. This sample begins with a new starter that is not bubbling on day four.

  1. Recognize the problem

    Each entry starts with an observable sign, so you can find the part that matches what is happening in your jar.

  2. Compare causes and next steps

    For a quiet new starter, the entry points to room temperature and explains how warmth, continued feeding and more time fit into the next step.

  3. Keep a prevention note

    The same entry ends with a temperature range for building a new culture. The format repeats: cause, fix, prevent.

A sample of the troubleshooting format, alongside chapters on starter care, dough and baking.

VI. Behind the books

From the Medieval Way series to your kitchen.

Medieval Way explores traditional skills through its video series and digital field manuals. The Bakery books bring the bread-making side of that work into a format you can keep beside you as you bake.

The three volumes have distinct jobs: recipes to follow, sourdough techniques to understand, and ingredients and tools to look for. The pages shown here come from the books themselves, so you can see the detail and decide which volume fits your next step.

VII. If you want all three

Three books. One complete collection.

Put the techniques to work with Practical Recipes, and use the Sourcing Guide to find the flour, grains and equipment for your next bake.

VIII. Before you order

A few practical questions.

Is this a recipe book?

It focuses on sourdough technique: the starter, dough, fermentation, baking and troubleshooting. Practical Recipes is the separate recipe volume.

Can I start without an existing starter?

Yes. The starter chapter covers building a culture as well as feeding, storing and reviving it.

What does the troubleshooting section cover?

The Rescue chapter brings together twenty-five failures by stage, so you can look up a problem where it happens in the process.

How do I receive the book?

This is an e-book, not a printed book. Your download is delivered after purchase. You can read it on a phone, tablet or computer.

Can I buy just this book?

Yes. The single book is selected by default. The Collection upgrade is optional, and you can remove it before continuing to checkout.

What if it is not for me?

Your purchase comes with the same 14-day money-back guarantee as our other digital books. Contact us if you need help with your order.
