The method is not hard; the waiting is. This guide shows you how to build a starter, read it, and plan each stage around a working day, so the dough fits your schedule instead of the other way round.
-
Build your starter
A day-by-day method for making a starter from flour and water, and how to keep it healthy.
-
Plan around your day
Sample schedules for weekdays and weekends, from feeding the starter to baking.
-
Fix what went wrong
Flat, dense, gummy or too sour: what causes each problem and what to change next time.

What you receive
The Sourdough Kitchen
Nine chapters covering how a starter works, building and feeding your starter, ingredients and hydration, mixing and stretch-and-folds, bulk fermentation, shaping, proofing, scoring and baking, and troubleshooting.
Questions
Before you buy
Straight answers about what this is, who it suits and how you receive it.
What exactly is included?
The Sourdough Kitchen as a digital eBook. Nine chapters covering how a starter works, building and feeding your starter, ingredients and hydration, mixing and stretch-and-folds, bulk fermentation, shaping, proofing, scoring and baking, and troubleshooting. There is no physical item.
Who is this guide for?
People who want to make sourdough at home and have baked at least a simple yeasted loaf before. It works with a standard home oven.
Is it suitable for beginners?
It helps to have baked a basic loaf first. If you have never baked bread, The First Loaf is a better starting point.
Do I need the other Karsebe guides?
No. It works on its own. The First Loaf is a gentler start, and The Home Bakery Year takes both further across a full year.
How do I receive my eBook?
Your eBook is delivered electronically after purchase, so there is nothing to wait for in the post. If you have any trouble accessing your download, contact our support team and we will help.
Is this a physical book?
No. This is a digital product only. No printed book or other physical goods will be shipped.
Will it work with my flour and oven?
The guidance is written for ordinary home ovens and widely available flour, and it explains the reasoning behind each step so you can adjust to your own kitchen. Room temperature, flour and ovens vary, and so do results from one kitchen to the next.
What is the refund policy?
Refunds for digital products are handled according to our Refund Policy. Please read it before you order, and contact us if anything is unclear.
