When I realized Daisy Madre was truly broken, my first reaction was panic.

For a moment I thought:

What am I going to do? I have no starter to make bread.

But after taking a few breaths I remembered something important. Years earlier I had preserved Daisy by spreading some of her on parchment paper, drying it, and blending it into a powder that I stored in the freezer.

So I still had Daisy.

That realization immediately calmed me.

Rehydrating a dried starter usually only takes a few days. My assumption was simple: revive the starter, place it back in the sourdough home at 16°C, and Daisy Madre would return.

But this is where I learned something humbling.

Daisy Madre is not easily recreated.

What I had preserved in the freezer was not Daisy Madre. It was the older Daisy I had known for years, which I now realized had likely been slightly acidic even then.

And freezing a starter brings another complication. Many of the microbes survive, but not all of them. The ecosystem must rebuild itself once it is rehydrated.

That means time.

And the right environment.

The Role of Enzymes

At this point I had already begun learning about the balance between yeast and lactic acid bacteria, but there was a third force in the system that I was only beginning to understand.

Enzymes.

Unlike yeast and bacteria, enzymes are not living organisms. They come from the flour itself. Grain naturally contains enzymes designed to break down proteins and starches during germination.

When flour is mixed with water, those enzymes become active.

Two types matter most in sourdough:

Amylase

Breaks down starch into sugars that yeast and bacteria can eat.

Protease

Breaks down gluten proteins.

Protease activity is what leads to proteolysis — the weakening of gluten structure over time.

And acidity accelerates this process.

So when a starter becomes too acidic, protease enzymes begin breaking down the gluten network faster and faster. The result is a starter — and eventually a dough — that becomes too extensible and weak.

Understanding this connection helped me realize why Daisy Madre had been so extraordinary.

Her ecosystem had reached a balance where yeast, bacteria, and enzyme activity were all working in harmony.

Broken Daisy had lost that balance.

Resetting the Ecosystem

My first goal was not to recreate Daisy Madre immediately.

It was simply to restore Old Daisy — the strong starter I had been using for years.

To do that, I began feeding Broken Daisy at a very high ratio: 1:20:20.

The reason for this was simple.

The less old starter you transfer into the new feeding, the less acid you carry forward.

Each feeding diluted the accumulated acidity and gave the yeast population a chance to rebuild.

At the same time, I kept Daisy at 23°C (73°F).

This was difficult emotionally because the sourdough home at 16°C had been so magical. Every instinct told me to put her back there immediately.

But the science said otherwise.

At this stage, the ecosystem needed warmth so the yeast population could recover and compete again with the bacteria.

Only once the system regained balance would the cooler temperature help stabilize it again.

So I stayed patient.

And I kept feeding.

Watching the Signs

During this recovery period, every feeding became an observation.

I watched how quickly she rose.

I looked at the webbing inside the jar.

I examined the surface texture.

Was it doming?

Was the surface creamy?

Were bubbles appearing above the surface or only beneath it?

And most importantly, I began measuring her pH every day.
