How To Start Sourdough Starter

Not only does keeping sourdough starter in the kitchen give you an endless supply of yeast, it makes for some of the most amazing baking!

Prep Time 2 minutes

  • 30 grams Flour
  • 30 grams Water


  1. Find a glass or plastic container large enough to keep your starter in. 

  2. You will also need a piece of cloth and a rubber band to place on top of the container.

  3. Place your container on the scale and turn it on. Then push the tare button. Then add 30 grams of flour. It can be any flour other than a nut flour. All-purpose will work just fine.

  4. Push the tare button again and add 30 grams of water. If you have city water I find it best to filter it first. Give it a good mix with plastic, silicone, or wooden spoon. Do not use metal. 

  5. Cover with a cloth and hold it on with a rubber band.

  6. Then for the next 5-7 days add that same amount of flour and water twice a day. I like to keep it about 12 hours apart to keep it healthy.

  7. After about 5-7 days it should be ready to start using in recipes. You will know when you start to see lots of bubbles at the top of your starter a few hours after feeding it.
