Sourdough Pizza Basics

What actually changes

Flavor. Wild yeast and lactic acid bacteria together produce acids that commercial yeast does not. That is the whole reason to do this, and it is a real difference rather than a subtle one.

Timeline. A starter is slower and less predictable than instant yeast. Budget 24 to 48 hours rather than 4 to 24.

Extensibility. The extra acidity and longer ferment relax gluten further, so a well-managed sourdough pizza dough often stretches beautifully. Pushed too far, the same mechanism goes past relaxed into slack and tearing.

Browning. More available sugars from the longer enzymatic breakdown, so it colors a little faster.

What does not change

The bake. Surface temperature, effusivity, preheat length, topping moisture - all identical. A sourdough base on an underheated stone is exactly as pale and floppy as a commercial-yeast one.

A workable timeline

Day 1 morning. Feed the starter. It should be at peak - doubled, domed, bubbly - about four to eight hours later, and that peak is when you use it.

Day 1 evening. Mix. Around 15 to 20 percent starter as a proportion of the flour weight. Bulk ferment at room temperature for two to four hours, with a couple of folds in the first hour.

Day 1 night. Ball, into individual containers, into the fridge.

Day 2 or 3. Out one to two hours before baking, then bake. Twenty-four to forty-eight hours of cold retard is the usual window.

The two adjustments people miss

Use less starter than a bread recipe suggests. Bread recipes often run 20 to 30 percent. For pizza, 10 to 20 percent gives you a slower, more controllable ferment and a dough that is still extensible when you want to stretch it thin.

Watch the dough, not the clock. A starter's activity varies with its feeding schedule, its hydration, the flour and the room temperature. Every timing above is a starting estimate. The poke test is the actual instrument.

The equipment that matters, and the equipment that does not

A fine scale matters. Starter percentages are small enough that a 1 g kitchen scale is marginal, and salt at 2 percent of flour weight is a number you genuinely want right. A 0.01 g pocket scale is the cheapest useful addition.

Clear containers matter, for the reason above: you read a sourdough ferment by what the wall shows you.

A banneton does not matter here. It is a bread tool that holds a loaf's shape upright, and pizza dough wants to relax outward - banneton versus dough tray.

A proofing box mostly does not matter, unless your kitchen sits below about 65 F. See the temperature guide.

Where it goes wrong

Using a starter that is not at peak. Under-active starter gives a dough that never really rises; over-hungry starter gives sharp, acetone-ish acidity.

Treating the timeline as fixed. A recipe's hours assume a room temperature and a starter that are not yours.

Over-fermenting in the fridge. Sourdough carries on working at fridge temperature more than commercial yeast does. Days three and four are less reliable than they are with a yeasted dough.

Expecting it to fix a bake problem. It will not. If your base is pale, that is surface and temperature, and it is the same conversation whatever raised the dough.
