Part IX
One of the most important things I learned through this journey is that a sourdough starter can look healthy and still be out of balance.
For seven years I believed Daisy was a strong starter. She rose beautifully. She often tripled. She had webbing in the jar and produced good bread.
Everything I had ever been taught said those were signs of a healthy starter.
But after experiencing Daisy Madre, I realized there are levels of strength that most bakers never see.
And once you see them, you can never unsee them.
Learning to read a starter means learning to observe surface texture, bubbles, rise pattern, webbing, and strength. All of these clues together reveal what is happening inside the ecosystem.
⸻
The Surface
The first thing to observe is the surface of the starter.
Old Daisy
Old Daisy looked like what most sourdough starters look like.
The surface was clearly domed. The edges lifted away from the glass and the top formed a rounded mound.
But the surface itself was textured, almost like linen fabric. It had a slightly grainy appearance, similar to a canvas or a lightly textured stucco wall.
It was matte rather than shiny.
If you looked through the side of the jar you could see thousands of tiny bubbles pushing upward, creating the dome. But those bubbles stayed beneath the surface.
You never saw large bubbles on top.
⸻
Daisy Madre
Daisy Madre looked completely different.
The dome disappeared entirely.
Instead the surface became flat, smooth, and glossy, almost as if someone had poured a thin layer of glass over the top.
It looked creamy and alive. The color even appeared slightly different—more creamy yellow rather than beige—because the surface was so smooth and reflective.
But the most dramatic difference was the bubbles.
They appeared on top of the surface, not hidden beneath it.
Large, round bubbles pushed upward with very thin membranes. You could see the entire top of the bubble exposed above the starter.
The entire surface looked alive.
When I opened the lid of the sourdough home, Daisy Madre looked like a living volcano—bubbles rising, expanding, popping, and reforming.
It truly looked like a living creature breathing.
⸻
Broken Daisy
Broken Daisy looked weak immediately.
The surface was flat, but not smooth like Daisy Madre.
Instead it was dull and uneven, covered in tiny pinholes where gas bubbles tried to form but immediately collapsed.
The rise was minimal—only about 25%.
The starter looked weak and lifeless.
If I tilted the jar, the starter would slowly pour like thick batter.
A healthy starter should never pour like that.
At that stage the acids had broken down the gluten structure so much that the starter had lost its strength.
⸻
The Bubbles
Bubbles tell an enormous story about what is happening inside a starter.
Bubbles Under the Surface
When bubbles stay under a thick domed surface, it means the gluten structure is not strong enough to trap large gas pockets.
The carbon dioxide produced by yeast is there, but it forms many small bubbles rather than fewer large ones.
These bubbles push the dome upward but remain hidden beneath the surface.
That was Old Daisy.
⸻
Bubbles On the Surface
With Daisy Madre the bubbles were completely different.
They rose above the surface, forming round balloons with thin membranes.
This tells you two things at once:
1.Yeast are producing abundant carbon dioxide.
2.The gluten structure is strong enough to trap large bubbles.
The gluten network has the perfect balance of elasticity and extensibility—strong enough to hold gas, flexible enough to stretch.
That is exactly the balance required to produce large alveoli in bread.
⸻
The Rise Pattern
Another important clue is how quickly the starter rises.
Many people believe that a starter that rises extremely fast is the strongest starter.
I learned the opposite can sometimes be true.
If a starter rises too quickly, it can indicate an ecosystem dominated by bacteria and acids rather than balanced yeast activity.
Old Daisy often tripled in four to five hours in my warm kitchen.
That sounds impressive, but it was actually a sign that the system was not ideally balanced.
Daisy Madre behaved very differently.
At 16°C (60°F) she took almost 24 hours to reach peak.
That slow fermentation allowed yeast and bacteria to remain balanced.
And the most remarkable difference was the peak window.
Old Daisy had about a 30 minute window where she was truly at peak.
Daisy Madre held her peak for almost three hours.
For those three hours she looked exactly the same—alive, bubbling, and strong.
That extended window is incredibly valuable for baking.
⸻
The Webbing
Another way to read a starter is by looking at the gluten webbing when it is poured from the jar.
Most starters show some webbing if they are reasonably healthy.
Old Daisy always had webbing. I even photographed it many times. The strands were visible and fairly strong.
But once I saw Daisy Madre, I realized that Old Daisy was only medium strength.
Daisy Madre’s webbing looked almost like a pasta madre starter used in Italian panettone baking.
The strands were incredibly elastic and organized, forming thick interconnected networks.
It looked almost like a piece of art.
Seeing that webbing made me instantly realize what true starter strength looked like.
⸻
The Feel
You can also read a starter by how it feels.
Old Daisy could be poured from the jar if tilted.
Daisy Madre could not.
Even after sitting at room temperature for a while, Daisy Madre remained thick and elastic. I often had to remove it in large blobs with a spatula.
It felt extremely strong.
The first recipe I baked with Daisy Madre—my Nordic rolls—required adding extra liquid because the starter itself was so strong.
⸻
Signs of an Acidic Starter
There are several clues that a starter is drifting toward acidity.
These include:
• pinhole bubbles across the surface
• dull matte texture
• bubbles remaining under the surface
• weakening gluten strands
• starter becoming pourable
• sour or vinegary aroma
None of these signals necessarily mean a starter is unusable.
But they do indicate the ecosystem is drifting away from balance.
⸻
The Moment Everything Changed
The moment I realized I could finally read Daisy felt empowering.
Knowledge does that.
When you understand what you are seeing, you stop guessing and start guiding the process.
For years I had worked hard on my technique without realizing the limitation was in the starter itself.
Once I understood that, the path forward became clear.
⸻
What I Tell Beginners
If someone asks me how to know if their starter is healthy, the first question I ask them is simple:
What is your goal?
If the goal is simply to bake bread for your family, the traditional signs—rise, smell, and bubbles—are enough.
But if someone wants to explore the craft more deeply, the starter must be managed with greater awareness.
The foundation of bread is the starter.
If the foundation is not balanced, the results will always be inconsistent.
⸻
The Biggest Misconception
The biggest misconception in sourdough baking is that a starter that rises high and forms a dome must be perfect.
I believed that for years.
Now I know that a starter can look strong and still be slightly acidic.
And that small difference can determine whether your bread produces small bubbles or large open alveoli.
Learning to read your starter is the first step toward mastering that difference.

I did not come here to persuade.
I came to share what I had learned,
and to leave the choosing in other hands.
