Essential Guide to Creating a Sourdough Starter

Welcome to the beginning of your sourdough journey! Sourdough is an incredibly fun way to make fresh, delicious bread for your family and friends. Creating a sourdough starter can feel like a daunting process but it is so worth it! This post will teach you how to create and maintain a sourdough starter, but beware, it might lead to sourdough taking over your life!

What is a sourdough starter?

A sourdough starter is a combination of flour and water that has been allowed to ferment. The naturally occurring yeast and bacteria in the flour will essentially “eat” the carbohydrates in the flour, producing carbon dioxide which is what causes the bread to rise. The process also produces lactic acid which is what gives sourdough its signature tangy flavor. Once your starter is established, you will have a stable culture of yeast and bacteria that you will regularly feed with more flour and water.

Ingredients

One of the best things about a sourdough starter is that it only contains two ingredients! Flour and water. I recommend using an unbleached, organic flour. You can use bread flour if you want, but I haven’t noticed a significant difference in the quality of my bread and I personally don’t think it’s worth the price. I usually use unbleached, organic all purpose flour because it is more cost effective. You will also want to use filtered, distilled or boiled water. Tap water can contain chlorine and other additives that might affect the quality of your starter.

Tools

You don’t need many tools to create a sourdough starter, but there are some things that will make your journey easier. To start, you only need a glass bowl or jar (do not use metal as it can interact with the yeast and bacteria), a spatula or wooden spoon, and some tool for measurement. I recommend using a food scale for better accuracy, but it is possible to create a starter and bake sourdough using measuring cups. I prefer to use mason jars to store and maintain my starter because I have so many on hand, but this KneadAce basic start kit is great option as well, and honestly, the spatula is the shining star of the kit – I use it every single day!

Sourdough Starter

Create your own sourdough starter from scratch and use it to make delicious bread, crackers, pizza dough and more.

Equipment

  • 1 glass jar with loose fitting lid or cloth
  • 1 food scale (measuring cups work too)
  • 1 spatula or wooden spoon

Ingredients
  

  • 10 grams flour organic, unbleached
  • 10 grams water filtered or distilled

Instructions
 

  • In the morning, mix 10g flour and 10g filtered water in a glass jar. Cover loosely with a lid or a cloth and allow to sit at room temperature overnight. If you don't have a food scale, use your smallest measuring cup. Ex: 1/4c flour and 1/4c water.
  • The next day, you should have 20g of what is now your starter. Add 20g filtered water and 20g flour. Mix well and allow to sit at room temperature overnight.
  • The next day, you should begin to see some bubbles forming, though the starter won’t start “growing” much yet. Continue to feed your starter daily with a ratio of 1 part starter, 1 part filtered water, and 1 part flour, feeding it around the same time each day. At this point, you may want to discard some of the starter before feeding so you aren't exponentially growing your starter each day(see note below).
  • Continue to feed your starter every day for at least a week. Throughout the week, you should start to see more and more bubbles and your starter will start to “grow” after each feed. Your starter is ready to use when it is at least doubling in size between feedings. You can also test your starter to see if it is ready to use by dropping some into a bowl of water. If it floats, it's ready to use!

Notes

I like to do what I call “micro feedings” when establishing or building up my starter. Many recipes will ask you to use large quantities of flour such as 100 grams, 1 cup, etc. but that can become a huge waste. Building and maintaining a starter is all about ratios, so any amount works. You want to maintain a ratio of 1 part starter, 1 part water and 1 part flour, so this could be 10g of each, it could be 30g, it could be 1 cup – you get the picture. The measurement doesn’t matter as long as the ratio stays 1:1:1. By using small amounts of flour, or “micro feeding,” you can significantly cut down on the amount of waste. Then, when you go to bake, stop discarding and just gradually increase the amounts until you have enough to bake with. 

Tips

  • Feed your new starter daily for a couple weeks to get it nice and strong before baking. Continue to feed it daily if you are using it regularly.
  • If, like me, you usually bake on the weekends, you can let your starter go a few days without feeding, just make sure to feed it every day for 2-3 days before using it to bake again. 
  • You can place a rubber band around the jar lined up with the top of your starter right after feeding, that way you will be able to see how much it grows. You can also use a dry erase marker to draw a line on the jar at the top of your starter.
  • You want to bake with your starter when it is at its peak, meaning it has reached its highest point before it begins to fall. After getting familiar you will be able to tell when the peak is. 
  • Once your starter is more established, you can keep it in the fridge when not using it. It can go several weeks between feedings when stored in the fridge. When you want to use it again, just bring it to room temperature and feed it consistently for a couple days to revive it. 
  • I often store my “mother starter” in the fridge. When I want to bake, I will take some of the starter out of the fridge, feed it, and leave it on the counter, returning the rest of the “mother” to the fridge. It is usually ready to go in a couple days. 
  • Make sure to feed your refrigerated mother starter monthly at a minimum.
  • Name your starter! If you name it, you will be more likely to feed it and care for it regularly. My starter’s name is Queenie.
