Bread Baking 300: For the Love of Sourdough | Lesson 1
There is no sourdough bread without a starter.
Flour, water, and time create a living culture that can eventually raise a loaf of bread. Making one isn't particularly difficult. The part that often makes sourdough feel difficult is knowing what you're looking at once you have one.
Is it hungry?
Is it rising?
Has it reached its peak?
Did you miss the window?
Is that liquid on top a disaster?
And perhaps the question every new sourdough baker eventually asks: Did I kill it?
That's why the first lesson in Bread Baking 300 isn't simply about making a starter. We're learning to read the jar.
The Scale Is Training Wheels. The Jar Is the Teacher.
When you're first learning sourdough, weighing your flour and water gives you consistency. That's useful because it removes one variable while you're learning what a healthy starter looks, smells, and behaves like.
For a 100% hydration starter, flour and water are equal by weight, not by volume.
But I don't want the number on the scale to be the only thing you understand.
I want you to notice the texture immediately after feeding. Watch where the starter sits against the rubber band. Notice the small bubbles that begin to appear. Watch the top begin to dome as the starter rises. Look through the side of the jar and see the structure developing inside.
Then keep watching.
Eventually the dome flattens. The starter begins to fall. A fresh high-water mark may be left on the glass.
That entire cycle is information.
Once you understand it, you're no longer simply following sourdough instructions. You're working with your starter.
Starting a Sourdough Starter From Scratch
A starter begins simply with flour and water.
For the method we're using in Bread Baking 300, we begin with a small amount so we can establish the culture without creating unnecessary waste.
During the first several days, the jar may behave in ways that surprise you.
You may see very little activity at first. Then it may suddenly become extremely bubbly and active. After that early burst, it can become quiet again.
This quiet period is where many new bakers assume something has gone wrong and start over.
Don't judge a young starter by one exciting day or one quiet day. Continue the feeding routine and watch how its behavior develops over time.
A mature starter should demonstrate reliable activity after feeding, including a predictable rise and substantial increase in volume. Temperature, flour, feeding ratio, and the condition of the starter all influence how quickly that happens.
Learn the Four Stages of Your Starter
Instead of memorizing an exact number of hours, learn to recognize the stages your starter moves through.
Hungry
A hungry starter has already consumed much of its available food. It may have fallen significantly from its highest point, smell noticeably sharp, or develop liquid on top after extended neglect.
It needs food.
Just Fed
Immediately after feeding, the mixture is comparatively smooth and thick. The jar is marked at this starting level so you can see exactly how much it grows.
Now leave it alone and let fermentation do its work.
Rising
As fermentation becomes active, bubbles develop throughout the starter and its volume increases. The top may begin to curve upward.
It's active, but that doesn't automatically mean it has reached its strongest point.
Keep watching.
Peak
Near peak activity, a healthy starter has expanded substantially and is filled with bubbles. The top may be gently domed and the structure looks light and aerated.
This is the stage we want you to learn to recognize visually rather than depending on a gimmick or a single arbitrary time on the clock.
Your Starter Has a Schedule, But It Isn't a Clock
You'll hear sourdough instructions such as "wait eight hours" or "feed every twelve hours."
Those times can be useful reference points, but your kitchen isn't a laboratory.
A starter in a warm kitchen may move through its food faster than the same starter in a cool kitchen. A different feeding ratio changes the timing too.
This is why the rubber band around the jar is such a useful teaching tool.
Mark the starter's level immediately after feeding. Then watch what happens above that line.
You're learning its rhythm.
What Is Hooch?
A neglected starter may develop liquid on top. This is commonly called hooch and is a sign that the culture has gone a long time without fresh food.
Dark liquid on a neglected starter isn't, by itself, the same thing as mold.
Feed the starter and watch how it responds.
There are, however, times when I will discard a starter rather than attempt to rescue it. Visible fuzzy mold or pink or orange discoloration are reasons to throw it away, thoroughly clean the container, and begin again.
Don't Be Afraid of a Neglected Starter
A hungry starter and a dead starter are not the same thing.
If a previously healthy starter has simply been forgotten in the refrigerator, regular feedings can often bring it back to strong activity.
The important part is observing how it responds.
Is it producing bubbles?
Is it rising after feeding?
Is that rise becoming stronger and more predictable with subsequent feedings?
Those observations tell you much more than panic ever will.
What About Sourdough Discard?
When you maintain a starter, you'll remove a portion before many feedings. That portion is what we call discard.
And no, that doesn't necessarily mean it belongs in the trash.
I keep sourdough discard refrigerated for recipes such as flatbreads, crepes, pancakes, muffins, and other bakes. We'll get into discard recipes later in the series.
For now, save it.
Your Lesson 1 Homework
Start a jar.
Mark the level immediately after feeding and write down the date and time. Then pay attention.
Watch it rise.
Look at the bubbles through the side of the jar.
Look at the top.
Smell it.
Watch it reach its highest point and eventually begin to fall.
Do that repeatedly and you will begin recognizing the pattern without needing someone else to tell you what every bubble means.
That is the skill we're building.

Print it. Keep it near your starter. Get flour on it.
This isn't meant to be something beautiful that lives untouched in a binder. It's a working reference for your kitchen.
