Can You Believe It? You Can Actually Make Your Own Sourdough Starter From Scratch!

Writer: Lisa MillerLisa Miller

Creating your own sourdough starter can feel like a daunting task, but it’s actually a pretty simple and rewarding process. If you've ever gazed longingly at artisanal loaves in your local bakery, now is your chance to replicate that magic at home! Let’s dive into the world of sourdough starter—what it is, why you need it, and how to make it from scratch.


What is a Sourdough Starter?


A sourdough starter is a mixture of flour and water that captures wild yeast and bacteria from the environment. This blend ferments over time, creating a living, breathing starter that you can use for baking. It provides leavening, flavor, and a bit of magic—transforming simple ingredients into delicious bread!



Ingredients You Will Need


To get started creating your own sourdough starter, you’ll need just two ingredients:


  • All-purpose flour or whole wheat flour

  • Water (preferably filtered or non-chlorinated)


In terms of equipment, a glass jar, a spoon, and a kitchen scale (if available) will come in handy. Once you have everything, you’re ready to begin!



Step-by-Step Guide to Making Your Sourdough Starter


Day 1: Mixing


Start by combining 100 grams of flour with 100 grams of water in your glass jar. Mix well until there are no dry bits of flour left. Scrape down the sides, cover it loosely with a lid or cloth to allow air in, and let it sit at room temperature (ideally around 70°F to 75°F) for 24 hours.

Day 2: Feeding


Check your starter. You might see some bubbles forming, but it’s okay if nothing happens yet. Discard half of the mixture (about 100 grams), and add in another 100 grams of flour and 100 grams of water. Mix thoroughly and cover it again. Leave it at room temperature for another 24 hours.



Days 3-7: Repeat Feeding


Continue the feeding process every 24 hours. By this point, you should begin to see larger bubbles forming, and the mixture will start to rise and fall. On days 5-7, you might begin to notice a more tangy aroma—this is a good sign!



Testing for Readiness


Around day 7, your starter should be ready to use for baking. To test it, perform the “float test”—take a small spoonful of your starter and drop it into a glass of water. If it floats, it's active and can be used in your favorite sourdough recipes. If it sinks, give it more time and continue feeding it.



Maintenance and Storage


Once your sourdough starter is fully active, you can use it in recipes right away or store it for future use. To keep it healthy, maintain a weekly feeding schedule if kept in the refrigerator. For frequent baking, keep it at room temperature and feed it every day.



Conclusion


Making your own sourdough starter from scratch is not only uncomplicated but also incredibly satisfying. The best part? You’re cultivating a unique blend of wild yeast that reflects your kitchen’s environment. Grab your ingredients and let the fermentation begin—before you know it, you'll be on your way to baking mouthwatering sourdough loaf after loaf! Happy baking!
