How to Make a Sourdough Starter: Day Five

Sourdough Starter Day 5 Morning

Well, it’s definitely alive, but I was hoping it would have doubled in size by now.  I’ve decided that now is the time to start feeding it twice a day, morning and evening, and keep up the regimen until it gets to the point where it will double in size within four hours or so.  Once it gets there, I think it will be strong enough to bake with.  These photos were taken in the morning, about ten hours after feeding.

I am still feeding with the same amounts of flour and water – Discard half of what’s in the jar then stir in one cup unbleached all-purpose or bread flour plus 1/2 cup filtered water.  I fed my starter in the morning (after taking the above photos) then marked the level with a rubber band.

About 12 hours later, it had grown a bit more than before!  It’s not quite doubled, but getting much closer.

Here’s a view of the bigger, more robust bubbles.

Things are looking good. I fed it once more before bed and will continue the twice daily feedings tomorrow.

Although this culture is a bit sluggish, we’re definitely getting somewhere.  I can still smell a hint of pineapple (I can taste it, too), but I think that will be gone after a couple more feedings.  I’m still not really sure how I feel about the pineapple juice method.  It’s not any faster than starting with flour and water, but lots of people swear by it and it’s working for me even if it’s a bit slow.  Whether you use water or pineapple juice, the biggest key to cultivating a sourdough starter is patience.

So, let’s talk a bit more about what’s actually been happening during this experiment.  Although I’ve been referring to my jar of bubbly batter as a sourdough starter throughout these posts, it’s technically called a culture until it’s strong enough to bake with.  Once it’s mature, it becomes a real sourdough starter, also known as a levain.  But I think it’s fun to come up with your own name for your starter once it has matured.  The last one I cultured at home was named Lyle (after Lyle Lovett, of course).

During the culturing process, we are trying to encourage the growth of wild yeast and certain benign bacteria.  It’s a symbiotic relationship – these wild yeast thrive in an acidic environment, so they like the lactic and acetic acids produced by the bacteria.  The yeast helps our bread rise, but it’s the acids produced by the bacteria that give the dough that distinctive sourdough tang.

Although it is commonly believed that we are trying to “catch” wild yeast from the air (and it’s true that wild yeast are everywhere), the truth is that the yeast is already in the flour.  From what I understand, whole grain flour, especially rye, is a better source of this wild yeast than white flour, so that’s why we started with whole rye or wheat flour.  Fruits, such as grapes, are also great sources of wild yeast, so you’ll see lots of different methods for cultivating a starter, including ones that use wild grapes.  No method is better than any other.  You can try whichever one sounds good to you and it will be the right way as long as you end up with a jar full of a bubbly batter that smells pleasantly sour.

Once you have a robust starter, you won’t have to keep feeding it twice a day (I’m sure that’s a relief!).  You can safely store your starter in the refrigerator, where it will slow down then basically go dormant.  It’s recommended to take it out and feed it once a week to keep it healthy, especially if it’s a newly established starter.  You can also dry or freeze small amounts of it to keep on hand in case you do accidentally kill the poor thing.  However, I’ve found that once you have a good strong starter, it’s pretty hard to kill as long as you keep it refrigerated.

Although the culture I’m creating right now is being fed with white flour, that doesn’t mean you can’t keep a whole wheat starter.  You can feed your starter with whole wheat from the beginning and keep it that way or you can convert a white starter to whole wheat by changing its diet (and vice versa).  There are no hard and fast rules when it comes to sourdough.  Experiment and have fun!

Once you have a mature starter, there are lots of ways to use it even if you don’t feel like baking bread.  I made the most delicious pancakes this morning using a cup of one of my well-established starters, 2 cups of freshly ground whole spelt flour, buttermilk, eggs, and melted butter.  It was a recipe adapted from King Arthur Flour and it couldn’t have been simpler to make.  You can make pancakes, waffles, muffins, cakes, biscuits, and more.  My friend Linda from Salty Seattle has even been experimenting with sourdough fettuccine and I’m really hoping she’ll tell us about it soon.

Once my new starter has matured (hopefully in the next couple of days), I’ll start experimenting with it and sharing recipes – it should tie in nicely with the October Unprocessed Challenge I’ve signed up for next month.  This is going to be fun and I’m really glad you guys are along for the ride!

I’ll be back tomorrow with another starter update and information on the health benefits of sourdough.  Yep, it turns out that sourdough may actually be better for us than standard whole wheat bread.  Stay tuned.

Want to create your own sourdough starter?

Here are the instructions (click on the links for photos):

Day One: In a small bowl, mix one cup of whole wheat or whole rye flour with 3/4 cup (6 oz) canned pineapple juice (at room temperature) until all of the flour is hydrated.  Scrape mixture into a quart-size wide mouth glass container, such as a jar or glass measuring cup.  Mark the level of the starter with a piece of tape or rubber band. Cover the container with a paper towel, cheesecloth, or coffee filter and secure with a rubber band.  Leave at room temperature for 24 hours.

Day Two: You probably won’t notice much change at this point.  Scrape the contents of the jar into a mixing bowl and add 1 cup of unbleached all-purpose or unbleached bread flour plus 1/2 cup pineapple juice (make sure juice is room temperature).  Mix until all ingredients are evenly distributed.  Wash and dry your glass container and scrape the mixture into the container.  Mark and cover the container just like day one.  Let sit at room temperature for 24 hours.

Day Three: You may notice some activity at this point.  The mixture may have risen some and there might be bubbles.  Regardless of whether you notice any fermentation or not, discard half of the mixture (or give it to a friend to cultivate), and mix the remaining half with 1 cup of unbleached all-purpose or bread flour and 1/2 cup filtered water (make sure water is room temperature).  Wash and dry your container and scrape the mixture into the container.  Mark and cover as before.  Let sit at room temperature for 24 hours.

Day Four: The mixture should have at least doubled in size at this point.  If it seems to be sluggish and hasn’t doubled in size, allow it to sit at room temperature for another 12 to 24 hours.  Otherwise, repeat instructions for Day three.

Day Five: Feed the starter (repeating day three instructions) first thing in the morning and then again in the evening (about 12 hours apart).

Day Six: If your starter has been very active and always doubles in size (or more) between feedings, then your starter is ready to bake with.  You may also choose to refrigerate your starter at this point and slow down the feedings to once a week.  If you’d like to bake some bread, here is a basic sourdough bread recipe to get you started.  If your starter still seems a little sluggish, continue with the twice daily feedings as above.

Day Seven: Same as above.

If you’d like to play along, I’d love to hear about it.  Please feel free to share photos of your sourdough starter experiments on the Pinch My Salt Facebook page.  If you’re a blogger and decide to write about the process, please share your links with me so that I can share them with others.

    I really appreciate your posting this Sourdough starter recipe. I have just made my own for the first time from KAF Website. It seems to be mature at this time, but in reading the Bread Bible by Rose Levy Beranbaum, I decided to make it into a “Stiff Starter.”

    So, can you give me an easy explaination on how to use a stiff starter in a recipe that calls for a liquid starter, or would it just be easier to convert what the recipe calls for from a stiff to a liquid starter?

    I am so new at doing this and I am getting so confused when feeding the starter, but I keep separating my starter and adding the flour and the water and yes it is doubling in size, I think I am ready to start baking. Confused tho it said to use 1 just cup of my starter with the other ingredients now…but I have alot of the starter left over. Am I reading the directions wrong or what. HELP!!!

    I am trying this new starter for the first time. had good luck to start it doubled in size in two days, then it has quite rising all together. it just sits with no rise in it and I feed it twice a day on day five now using unbleached flour and spring water. should I start a new one or cross my fingers its going to wake up

    Hi Jerry. If that happens try throwing half of it away and adding more flour and water to refresh it. If push comes to shove you could always add a tiny pinch of yeast to help kickstart the process.
