Sourdough starter, step by step

Just flour, water and a little patience. I'll take you from your first mix to feeding and keeping a starter, and how to use it for bread and other recipes.

Who it is for

If you want to bake sourdough but don't have a starter yet, start here. No baking experience needed.

What you'll learn

  1. What a starter is and how it helps bread rise.
  2. What you need, and how to mix flour and water on day one.
  3. How to feed your starter and watch for bubbles and growth.
  4. How to judge when it is ready to use.
  5. How to keep, store and dry a little as a backup.

What you need

Whole wheat or rye flour, water, a jar or plastic container with a lid, a digital kitchen scale, a spoon, a label, and a rubber band or marker.

Questions before you start

How long does it take?

The course follows a seven-day schedule, with about five minutes of work most days. Your starter may take longer. Temperature and the starter itself make a difference, so watch the jar, not just the calendar.

Do I need to buy yeast?

No commercial or artificial yeast. We make our own from flour and water.

Do I have to feed it every day forever?

No. Once it is active, you can keep it in the fridge. In the course, I show you how to feed it weekly and prepare it for baking.
