Why the timing shifts

Very hot — avoid. Mold risk rises sharply above 85°F. Fermentation outpaces structural development. Levain becomes unbalanced toward lactic acid producers, creating cloying sour flavor. Only use briefly for refreshing starters or if absolutely unavoidable. Move dough to cooler location, or skip this bake and wait for cooler conditions. If baking must happen, reduce levain to 8%, bulk 90 min max, get into refrigerator immediately after shaping.

Technique for Sourdough Naan

Mix dough with yogurt + water. 3h bulk. Divide into 100g pieces, short 1h proof. Stretch into teardrop shape. Cook on very hot cast-iron skillet (or under hot broiler) 90 sec per side. Brush with melted butter/ghee, optionally sprinkle fresh herbs (cilantro).

How the math works

Multipliers are piecewise-linear interpolations between reference points measured by Myhrvold et al. in Modernist Bread vol 3. 76°F is the baseline (1.0×); every 10°F drop roughly doubles fermentation time, and every 10°F rise roughly halves it.
