Everything you need to know — from the tools on your counter to the first bubbles in your jar.

To create your sourdough starter, you only need a few simple things.
A clear jar so you can watch your starter grow and bubble.
Precision matters — weighing ingredients gives consistent results.
Whole wheat or rye to start, then all-purpose for ongoing feeds.
Chlorine can slow fermentation, so filtered or bottled is best.
Mark your jar to track how much your starter rises.
For mixing — metal won't hurt, but wood feels right.
Once your starter is active, these tools will help you bake a beautiful loaf.
Gives your loaf shape and that gorgeous spiral pattern.
Traps steam for an incredible crust — the secret weapon.
For scoring beautiful patterns on top of your loaf.
Makes shaping dough and cleaning up so much easier.
For easy transfer into your hot Dutch oven.
To line your banneton and cover dough while resting.


It takes about a week of daily feeding. Here's the simple routine:
Combine 50g whole wheat flour and 50g water in your jar. Stir well, cover loosely, and leave at room temperature.
You may see a few bubbles. Discard half, then feed with 50g flour and 50g water. Repeat daily.
Bubbles should be more consistent. The smell may be tangy or even funky — that's normal! Keep feeding.
Your starter should double in size within 4–6 hours of feeding. Drop a spoonful in water — if it floats, it's ready!
