NY Style Pizza (Sourdough) at 78–82°F

Why the timing shifts

Warm kitchen or proofing box — ideal for accelerating fermentation. Ferment 25% faster than baseline. Good for schedule compression. Watch carefully — dough over-proofs quickly. Ideal for hot-weather baking when you want to get dough into cold retard before too much fermentation happens. Consider reducing levain to 12-15% to slow things back down.

Technique for NY Style Pizza (Sourdough)

Same as Neapolitan but higher hydration and add 2% olive oil + 2% sugar. Bulk 2h, cold retard 24-48h. Stretch to 14-16 inch round. Bake on preheated steel at 550°F for 7-9 min until cheese bubbly and crust golden-brown.

Why 78–82°F changes your timing

Sourdough is a living culture, and its yeast and bacteria speed up as it warms. Across the useful baking window (roughly 50–95°F) the rate follows the classic Q₁₀ relationship — fermentation runs about two to three times faster for every ~15–18°F of warming. At 78–82°F the net effect is a 0.75× bulk and 0.75× proof multiplier versus the 76°F bakery baseline, so every stage runs faster. That single number is why a formula's printed times only hold at the temperature they were written for — move the dough 10 degrees and the clock is wrong.

Worked timing at 78–82°F

NY Style Pizza (Sourdough) baselines from the recipe, multiplied by this range's bulk (0.75×) and proof (0.75×) factors. Treat these as a floor to start checking, not a finish line.

What to watch for at 78–82°F

Fermentation runs fast here, so the common failure is over-proofing — the dough balloons, then loses its spring and bakes up flat with a pale, gummy crumb. Set a timer as a floor, not a target, and start checking the dough by feel and jiggle early.

How to adjust your formula at 78–82°F

Because the culture is very-active at this temperature, drop your levain to about 10–15% and keep the bulk short so the fast rise doesn't out-run gluten development — otherwise the crumb goes gummy and the loaf spreads.

To land the dough in this range even when the room swings, use the desired-dough-temperature (DDT) method: dough temperature ≈ (flour temp + room temp + water temp + friction factor) ÷ 4. Solve for the water temperature you need — in a cool kitchen use warmer water; in a hot one, cool or even iced water — so the dough itself, not just the air, sits at your target.

Telling doneness by feel, not the clock

The times above are a guide; the dough is the real timer. Bulk is done when the mass has risen 50–75%, looks domed and bubbly, and jiggles like set custard when you shake the container — an aliquot jar (a small sample in a straight-sided container) makes the rise easy to read. The final proof is ready when a floured poke springs back slowly and only partway. These cues are identical at every temperature; only when they arrive changes — at 78–82°F, sooner or later by the 0.75× factor above.
