Why the timing shifts

Cool kitchen — spring/fall without heating, air-conditioned summer. Ferment 1.5× longer than baseline. Good flavor development territory. Dough develops more complex sour notes. Manageable schedule. Extend bulk and proof by 50% vs recipe defaults.

Technique for Pan de Cristal

Mix in stand mixer: all flour, 60% of water, oil, salt, levain. Gradually add remaining water over 5-10 min while mixing until dough is fully developed but extremely loose. 4 sets of coil folds every 30 min in first 2h, then rest for 2 more hours. Gently tip onto heavily oiled sheet pan. Cut into 4-6 rectangles with oiled bench scraper. Short 1h proof. Bake 500°F with steam, 18-22 min.

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.
