Sourdough yeast starter [infographic] and boule

This sourdough is the best bread I’ve made with a wild yeast starter.  It’s probably even the best bread I made ever. But before we get into that, let’s back up a little.

So, what’s a wild yeast sourdough starter?

It’s OG (Original Gangsta) yeast.  It’s what humans have used to leaven bread before the advent of commercial yeast.  It’s probable that wild yeast for bread was discovered when a person, thousands of years ago, left her flatbread flour mash outside in the warm air, accidentally, for a while.  When she came back, she saw that the mixture had bubbles in it.  Yes!  Yeast was growing and multiplying in her grain mash.  As an experiment, she baked and and found that it was fluffy and tasted awesome.

Thus, bread was born!

There’s some debate over where the natural yeast spores comes from.  Some people say the air.  Other people say it’s in the grain.  I tend to believe it’s the latter, as I’ve found that using bad grains (bleached flour) in your starter and bread kills the starter’s bread-raising properties.

Why bother with a starter when there’s commercial yeast available?

Commercial yeast is predictable, consistent, and takes a much shorter amount of time to raise bread.  Breads leaven with wild yeast take considerably longer, true, but it also creates bread with more flavor and a nicer aroma, in my opinion.  Wild yeast starters are often called sourdough starters; some breads made with starters do have a slight sour tinge that many (me included) find quite pleasant.

(But, it should be noted that bread and any other baked goods made with a wild yeast starter doesn’t have to be “sour.”  It can be manipulated and coaxed into different flavors.  Wild yeast is very malleable. And actually, a lot of “sourdough” breads we find at the grocery store are laced with vinegar or some other acid for the sour flavor.  I kind of doubt they are true sourdoughs.)

Lastly, you just feel deeply satisfied when you’ve made bread from a starter.  You feel self-sufficient and it’s an art form.

So enough blathering. How do you get a starter?

1. You can buy one.  Yeasties in starters are like sea monkeys in that they can be dried and suspended indefinitely.  So starters that you buy online will be in a powdery, dried form.  You just add water and the yeasties spring back to life.

2. You can find a local bakery that will give you some or sell you some.  I actually went this route before.  I have a kind friend who works at a restaurant and she hooked me up.

3. You can make your own!  I’ve also done this before and the current starter I have is one I made mixed with the one I got from the restaurant.  (It was too much for me to keep two going.)

I didn’t take pictures from the last time I made a starter, so I created a handy infographic for you guys.  :)  However, there are nuances an infographic can’t convey, so I’ve added notes at the bottom.

(Click for more of my food-related infographics.  For other food-related infographics, visit my Pinterest board.)

Here are my tips, learned from many, many failed attempts at making a starter:

1. The flour is the most important component.  You can’t get a starter from bleached flour, which is flour that’s been processed to look super white (and due to the bleaching process, is stripped of its natural “wheatiness,” which means no yeast spores to draw from).   Putting bleached flour in a starter will kill it.  I’m not sure why, but bleached flour is usually cheaper than unbleached.  It seems weird because you’d think the added bleaching process will drive up cost.  But anyway, sacrifice a few extra bucks and get unbleached all-purpose or unbleached bread flour (the difference is the protein content.)  I use all-purpose.  :)

I started my starter with rye flour, which some people say have more yeast spores to draw from.  Your starter is very delicate and weak in the beginning, so it needs all the help it can get.  (Later, it will basically become unkillable, unless there is serious neglect.  So yay!)  I found the rye flour at my local chain grocery store, in the bulk bins.  The brand was Red Mills.  I checked the date on the bin–the flour was ground in the last few months.  So I just scooped out as little as a 1/4 pound and was on my merry starter-starting ways.  (FYI, any whole grain flour will do.)

2. The actual measurement of flour to water isn’t so important as it is to keep doubling the amount of proto-starter.  So that’s why the infographic says you have to toss out half of the starter each time, before adding more flour and water.  That’s so the yeasties have enough stuff to snack on.

3. Some people say the chlorine in tap water can kill the yeasties.  This wasn’t a problem for me, here in Washington state.  I think if your water is drinkable from the tap, you’re okay.  But if you want to be absolutely sure there are no water issues, use mineral water or spring water.  (But don’t use distilled water!  It’s totally sterile and will not help the yeasties one bit.)

4. Around day 3 or 4 (the infographic is far more precise than this, but keep in mind that it’s different for everyone due to location and temperature and grains used), the starter will look like it totally died.  And if you’re like me, you will be totally discouraged and devastated.  But keep on with the twice-daily feedings!  The reason the starter appears to die because all the activity leading up to that point wasn’t due to yeast, but due to bacteria.  It’s a totally cruel fake-out, but getting to the “DEATH!” point is good because it means the bacteria are subsiding and giving way to the eventual yeast.

5. You’re supposed to do all of this in warmish temperatures, but it will happen in cooler temperatures, too.  It will just take longer.

6. I started my mixture with pineapple juice instead of water, for the first three days.  I’m not sure it made any difference, but supposedly, the acidity of the juice helps create a nice environment for the yeast to grow and the sugars in the juice gives them something to munch on.

7. Once you get your starter going and it’s doubling after every feeding, it’s ready to bake with.  You can keep its twice-daily feedings at room temperature for another week or so, to build up the flavor a little more, or you can refrigerate it and retard the rising.  Then, you can reduce feedings to once a week!  Low-maintenance, right?

8. I’ve seen starter methods that call for commercial active dry yeast.  I don’t recommend doing this.  These are two different kinds of yeast and the ones you want for the starter aren’t the ones in the commercial yeast.  Putting that stuff in your starter might just make things take longer.

9. After you’ve refrigerated, before you can bake again, you need to go through two “feedings” and until the starter can double its size again.

Enough of this, where’s the recipe?

Sourdough yeast starter and boule |

No-knead sourdough boule
Recipe type: Bread
Prep time: 
Cook time: 
Total time: 
Serves: 2-4
Yields 1 boule. Also, due to the small amount of starter in this recipe, this will take a looooong time to rise.
  • 60 grams sourdough starter (about ⅓ cup)
  • 420 grams all purpose flour (about 3 cups)
  • 250 grams of room temperature water
  • 1½ tsp of salt
  1. Pour the starter and salt into the water. Mix in a medium bowl until the starter is completely dissolved in the water.
  2. Add in the flour and mix with a spoon. Do some light kneading in the bowl, but don't really worry kneading it. Just worry about getting the mixture homogeneous. The long rise time will take care of building up the gluten in the bread. ;)
  3. Cover with plastic wrap and leave in a warm corner for 8 hours. YES. EIGHT hours. Nothing will happen during hours 1-6, and it will be super frustrating. But leave it alone overnight and you will see that it puffed up.
  4. Form the boule. Flatten and pull the dough out of bowl. Pull it over itself, again and again, to form a tight ball. Basically, gather from the center of the ball and pull the "skin" over the body of the dough ball to make it rounder and tighter.
  5. Liberally flour a clean, smooth surface, (your counter top?), an area a little bigger than the size of the dough ball (because it will rise!). Place the dough ball on top. Add more flour to the top of the guy. Cover with plastic so it doesn't dry out. And leave it alone for another 8 hours or so. (The times are not precise, so based on what your dough is doing, you may want to move onto steps sooner or later. I like big bubbles so I had loooong wait times.)
  6. After so-and-so many hours, your dough should be puffy and almost double in size. Preheat the oven to 400 degrees F. I flip a cast iron skillet over and also put that in the oven to preheat (I cook my bread on that bottom surface of the skillet, but a sheet pan will also do).
  7. Right before baking, score the top of the bread. I like to slash a big ol' square on it.
  8. Bake for about 35 minutes or until the bread is a light golden brown color and feels light for its size.
  9. Let it cool for at least 10 minutes before slicing and serving.

This bread has a long rising time because of the relatively small amount of starter I use.  I use a small amount because I like for it to develop more of a “sourness,” and the longer rising time allows for that.

I’m a very non-precise person and bread-making requires a fair bit of precision.  The good thing is if you don’t mind being surprised over how your bread turns out, then experiment and it’ll usually be okay.

But for more precision: the consistency and texture of your bread will largely depend on the hydration level of the dough.  Hydration is a percentage, which is calculated by comparing the amount of water (x%) to the amount of flour (100%).  So if a dough requires 100 grams of flour and 60 grams of water, the hydration of that bread is 60 percent, which is about where you want to hit for standard every day bread.  I will probably talk more about this later, when I OBSESS over pizza dough and baguettes.

Michael Ruhlman and the red cabbage method
Didn’t actually work for me, probably because my flour was bleached when I tried this method.  This reportedly worked for a lot of people.  And Michael Ruhlman is awesome.

Pineapple juice method
This totally worked for me.

  • Iona

    Hey there! I have just made a pretty cute lookin starter from your recipe – and have kept it up till day seven, going to make a loaf tomorrow I hope.
    I was wondering step 5 and 6 of your recipe though – do you mean you leave it on your counter for the second rise, then flip it onto a tray (I’m worried that this might make the rise deflate a bit?) and cover with a cast iron pot… I guess that the pot would create a steamy environment and make an extra crusty bread. Also what do you mean about preheating the pot… I haven’t heard of this before and I am intrigued!
    Pretty excited about what a joy this starter was to make! And thanks for the help! :~D

  • Vickie

    I haven’t made the bread yet but the starter will not stop growing. Every morning it is overflowing on the counter. I put it in a bowl and the bowl is full. It hasn’t been a week, can I make bread out of it?

    I just found this and love it! I’ve been feeding my starter for a full week now (every 12 hours, tossing half before each feeding). It still hasn’t hit the “dead” stage…when I open it after every 12 hours, it’s very airy and bubbly, and smells like sourdough — not unpleasant like it did in the beginning, but not “yeasty” either. It also doesn’t seem to be doubling in size. Could it be stuck at the bacteria stage? Is there a way to encourage yeast to grow more?

  • Gina Calabrese-Hendershot

    love this whole page and found it on pinterest. just started the starter to give it a go. i bought some hard white wheat berries and milled them. i was wondering what the consistency should be like when you combine your flour and water on the first day. mine was very dough-like and didn’t seem liquidy enough. i thought maybe bc of the freshly milled flour. also i just dipped my scoop in there. probably should have spooned it in. anyway, your thoughts? :)

  • Brittany Zampella

    Got my starter in the works thanks to your graphic and explanation! Hoping it turns out well so I can try out your bread recipe. Question for you in regards to that real quick. I have stone ground whole wheat flour, would that be okay to use instead of all purpose flour? Do you think I’d have to add more water to it or alter anything else in bread recipe if I’m using that kind of flour?

    • Stacy Nguyen

      Hi, Brittany! How did it work out for you? I hope you tried it with stone ground wheat with success! (It should’ve worked!) You may need to add more water to get the right consistency.

  • Kathleen

    What is the consistency of this supposed to be at the start? Is it supposed to be thicker like a dough or thinner like pancake batter? When I mixed it up last night (using whole wheat unbleached flour and spring water), it was thick like a dough I could knead. I added the second round this morning and now it’s so thick and sticky it can barely be stirred. Most of the other recipes I’ve read all said it should be like pancake batter, so I’m kind of confused! Thanks!

    • Stacy Nguyen

      Hi, Kathleen!

      The starter is pretty forgiving and its consistency can run the gamut between pancake batter and dough-like. if you can’t stir it, you can certainly add more water to soften it. It should be, generally, equal parts water and flour, by weight. In my experience, the slurrier (wetter) the starter, the faster the yeasties move through the mixture and the faster they eat up the flour and expel gas, lifting up the starter with bubbles. This isn’t bad or good, but I like my dough on the thicker side because sometimes with it’s too thin, the starter could rise/fall without me noticing it. With a thick mixture, the growth is more apparent.

  • Martina

    Hi! I’ve been waiting to try this for quite a while! I was wondering, can i basically use aby liquid instead of pure water (like tea, coffe, misc things) ? I’d like to experiment with all kinds of crazy combos and wondered if i could make a fall type breac using tea instead of water. Thanx!

    • Hey, Martina! Good question—I haven’t tried using other liquids, but I think that doing so can be problematic—if you’re starter becomes too acidic/basic, this or that, it could die on you. I suggest flavoring your bread with those crazy combos instead of the starter. So you can add your regular ol’ starter to different flours and water and add in instant coffee, molasses, garlic, onions, Skittles to the dough and see what happens. :) Sounds fun!

  • What size jar? Quart? Will a ‘canning jar’ do?

    • A canning jar will do very well! I keep about 1/2-1 cup starter around, so whatever will hold that amount will do.

  • tmcouch

    We are a gluten-free family and are trying to get away from yeast, too. A sour dough starter would be a perfect fit for us. Have you ever tried it with any gluten free flours such as brown rice or potato flour?

    • Hi, tmcouch–

      Unfortunately I haven’t tried this with gluten-free flours so I can’t speak to it. I’d be curious to see how it turns out if you do, though. Good luck!

    I am so excited to try this!! I have been wanting to do this for a while but have been intimidated. This makes it sound less complicated to me. However, I have two questions for clarification…at any point should there be a lid on the jar? Also, can I do this with whole wheat?

    • You’ll want a lid when you eventually store the jar in the fridge so that the top doesn’t get all dried out and crusty. I poke holes in the lid of my jar so that the container doesn’t explode from the gasses the yeast gives off. During the process itself, you can just place a damp towel/paper towel or loosely cover it with plastic wrap or the lid with holes. The idea is to keep out the fruit flies while letting the air in and out. It’s mostly to keep out the flies. ;) And yes, you don’t have to start with rye flour. But the whole wheat flour has to be unbleached. I’d try buying a small amount of unprocessed/organic yeast from the bulk bin to start off the starter and then later getting the big ol’ economical bag of flour to sustain/feed the yeast when it’s strong.

      • Denise

        Perfect!! Thanks so much!! I can’t wait to get started!!

  • Awesome infographic! Definitely going to have to try this sometime =)

    • Thanks! And good luck! I’m crossing my fingers for you. :)

  • I love the infographic! I had a nice starter going, but my husband found it in the back of the fridge and tossed it. =(

    Maybe it’s time to start a new one…

    • Hi, Stacy! I LOVE how you spell your name. ;D

      That’s so sad about your starter! But yes, glass half-full, it could be fun to start another. :)

      • Down with extraneous vowels! ;-)

  • You have to keep doing the toss and adding new flour etc until day 7?

  • I´ve tried to do recipes like this one in the past and …. all fails! But yours looks super detailed and i may do it again :D

    I like the flavour of sour bread, regular one is a little bit sweet if it makes sense ….

    • Hi, Noelia! I, myself, failed at making starters a whole lot before being successful. I found that the most important factor for me was ensuring that my flour was unbleached (haha!). Bleached flour really just kills the starter. And there’s also the fakeout around Day 3/4! Some recipes forget to tell you things go quiet for a bit before coming back to life, so I imagine some people will toss their starters in that time, without knowing that magic is about to happen. Here’s more information on the pineapple juice method, if you’re interested:

      I know what you mean about regular being too sweet!

      And yes, you have to keep tossing and adding flour through day 7. I’m sorry it wasn’t clear. I’ll amend the infographic later to reflect this. Thanks for pointing it out!
