Why the timing shifts

Hot kitchen — summer without AC, near-window light. Ferment nearly 2× faster than baseline. Not ideal — fermentation outpaces gluten development, leading to over-acidic flavor and collapsed structure. If unavoidable, use very low levain (10-12%), minimal bulk (2h max), and get dough into cold retard ASAP. Consider reducing bulk temperature by moving dough to cooler location (basement, refrigerator brief intervals).

Technique for Focaccia Genovese

Mix dough with olive oil incorporated. 3h bulk. Heavily oil sheet pan. Transfer, stretch to fill. Proof 90 min. Before baking: mix 2 tbsp olive oil + 2 tbsp water + 1 tsp salt, brush over surface, dimple aggressively. Bake 475°F 18-22 min until deep golden edges.

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.
