My Journey with Sourdough

My journey is probably much like yours. Scrolling through the ‘gram I would see loaves of bread and the word sourdough everywhere. Honestly, I’ve never had a taste for sourdough, at least that’s what I thought. Before I began baking, I had only had store-bought bread and maybe a sandwich here and there on sourdough. It wasn’t something I even thought to make myself. 

2020 happened and I began to reevaluate our lifestyle and felt a pull to slow down and embrace life’s simple pleasures a little more. We bought some chickens, planted a garden, and sourdough just seemed like the proper next step. Ha! Up until that point, I had never baked a loaf of bread and had no idea that bread could be made without store-bought yeast. 

My first sourdough starter was a failure. I used cheap flour and after weeks of following the steps I threw it away. Feeling determined, I googled my issue and found King Arthur flour as the most recommended flour for sourdough baking. I started over and this time it worked! 

What is Sourdough?

Sourdough is a naturally leavened bread which just means there’s no commercial yeast added to make the bread rise. (I told you we’re keeping it simple.) Instead, it’s fermented using a sourdough starter. It’s richer in nutrients and lower in gluten therefore making it easier to digest than breads made with traditional yeast. 

Sourdough Starter

Before you begin making bread, you’ll need what is called a starter. I’ve created a free download with easy-to-read, day-by-day steps to creating a homemade sourdough starter. 

A sourdough starter is made by mixing just two ingredients…equal parts flour and water! Yes, it’s that simple. I have step-by-step instructions for making your own sourdough starter here. Once you begin mixing flour and water in a jar, wild yeast and bacteria from the environment of your home will begin feeding off the flour causing it to multiply. Crazy huh? 

By feeding (sourdough jargon meaning adding flour and water to your starter) the starter regularly, it will gain strength and can eventually be used to make simple sourdough bread. This process of building your starter typically takes 1-2 weeks. 

Feeding Your Starter for This Sourdough Recipe

For this recipe, you’ll need an active fed starter. I recommend feeding it at night before bed so that it has a long rise time overnight and can be mixed the next morning. Another option is to feed your starter in the morning, mix it before bed, and then bake it the next morning. It really just depends on your schedule. 

Just make sure that 8-12 hours prior to mixing your bread, you feed your starter. For this particular recipe, you’ll want to scoop 2 tablespoons of your starter into a clean jar and then add 1 cup of flour and 1 cup of water.

Ingredients for King Arthur Sourdough

One added bonus of making fresh sourdough bread is that there are very few ingredients needed. 

• King Arthur Unbleached All-Purpose Flour
• King Arthur Whole-Wheat Flour
• Water (room temperature)
• Salt

​You will need high-quality flour with a protein percentage of at least 11.7%. Most quality flours display protein content on the outside of the packaging. I prefer King Arthur brand flour but I also purchase the Costco brand organic flour and it bakes just as well and is more affordable. 

Tools

There are a few tools that make baking sourdough a little easier but most are not necessary.

Weck Jars: My favorite!!
Dutch Oven
Banneton Basket: These are available in different sizes and shapes and are great for shaping your loaves during the bulk rise time. 
Parchment Paper: Keeps the bread from sticking to the bottom of the Dutch oven.
Bread Lame: This is for scoring your loaves before baking. You can also use a sharp knife to make your cuts.
Rice Flour: This isn’t necessary, but can be used to sprinkle on top of your loaves before scoring and will make your design more distinct. 
Cooling Rack
“>Heat-Proof Gloves– Using gloves to move your loaves in and out of the oven is a good idea. Bread bakes at a very high temperature and the slightest touch will burn.
​Dough Scraper: A tool used for scraping and lifting the dough. 
Serrated Bread Knife: This makes cutting into your loaves so much easier!

How to Make King Arthur Sourdough Bread

This bread bakes golden brown with a nice crust and perfect flavor. This recipe makes 2 loaves. 

Step 1:
12 hours prior to mixing your dough, feed your starter.

Into a clean jar add…

2 tablespoons of starter
1 cup of King Arthur Unbleached All-Purpose flour
1 cup of room-temperature water

Step 2:
After your starter has doubled, place 1 3/4 cups of room-temperature water into a large bowl. Add 2 cups of your active starter to the water and stir. Mix in 5 cups of King Arthur Unbleached All-Purpose flour and 3/4 cup of King Arthur Whole-Wheat flour into your bowl. Mix well until all bits of flour are moistened and you’ve formed a soft tacky dough. 

Cover with a damp towel and let rest for 20 minutes. 

Step 3:
After letting your dough rest, add 2 1/2 teaspoons of salt and knead the dough for an additional 4-5 minutes. You want a soft dough that’s somewhat tacky. Place the dough back into the bowl, cover with a plate or plastic wrap, and let your dough rise for 1 hour. 

Step 4:
After an hour, turn the dough out onto a lightly floured surface. Fold it like a business letter. Then do a quarter turn and fold it again and once more. Place to dough back into the bowl and let it rise for an additional hour. 

Step 5:
Turn the dough out onto a floured surface and divide in half with a dough scraper. Gently shape it into two rounds by gently cupping the dough, pulling and twisting it towards you while building surface tension.

Leave each round on the counter and cover with an upside-down bowl. Allow 20 minutes for the rounds to rest. Then, place each round into a fabric-lined banneton basket sprinkled with rice flour. Cover and rise for 2 1/2 hours.

Step 6:
About half an hour before baking, place your empty dutch oven inside the oven and preheat to 450 degrees. At the end of the rising time, turn your rounds out onto a piece of parchment paper. Using a bread lame, razor blade, or sharp knife, make 2 deep diagonal slashes into the rounds. Carry the dough by the corners of the parchment paper like a sling and very carefully place it into the preheated Dutch oven.  

Bake with the lid on for 20 minutes. Remove the lid and bake for an additional 20-25 minutes until the crust is golden brown. 

*Be sure to preheat again before baking your second loaf.

Allow the bread time to cool on a cooling rack for 1-2 hours before slicing. If you cut into your loaves too early the dough will be gummy. 

Storing leftover bread

It’s quite possible to devour an entire loaf at one meal but just in case you have leftover bread there are a few ways you can store it to keep it fresh.

• ​Place it in a paper bag.

• Wrap it in plastic wrap.

• Store as is but with the sliced side face down on a cutting board.

• Freeze for longer storage by wrapping your loaf tightly in plastic wrap and placing it inside a freezer bag. 

Tips for Successful Baking 

My greatest tip is to just keep trying. Ugly bread is still yummy! I’ve never had to toss a loaf. 

Fermentation (or rise time) is forgiving. If you see that you can’t bake it within the rise time window, you can always slow ferment in the refrigerator. 

Sample Baking Schedule

8:00 pm  Feed your starter the night before you plan to bake.

8:00 am  Mix your dough and let it rest. 

9:30 am Fold and turn. Rest for an additional hour.

10:30 am Divide and shape. Rise for 2-3 hours.

1:00 pm  Preheat oven and bake!

FAQ’s

Why is my sourdough bread not rising in the oven?
This is most likely because your starter isn’t strong enough. Over time the strength of your starter will increase and you will get a better rise.

Can I use a stand mixer?
Yes, you can use a stand mixer with a dough hook but I caution against it with this type of loaf. Using a stand mixer can cause over mixing which can lead to a bread that’s more dense. For best results, mix and knead using your hands.

​What if I want to use only whole wheat flour?
Bread that’s made with 100% whole wheat flour is typically very dense. 

Do I have to add whole wheat flour to this recipe?
No, you can replace the 3/4 cup of whole wheat with all-purpose if you like but the small amount of whole wheat gives a nice rise and texture. 

I am a huge advocate for just getting started. Not every loaf you bake with be perfect but just like with anything else, you will get better loaves over time. Don’t get caught up in all of the sourdough jargon! Just follow the recipe and you’ll become more knowledgeable over time.
