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 Sourdough English Muffin

Mix dough, 2h bulk. Refrigerate overnight (12-16h). Portion into 90g pieces, shape into rounds, dust with cornmeal, place in ring molds on parchment. Proof 60-90 min at room temp. Heat cast-iron skillet on medium-low (350°F), cook each muffin 7 min per side, flipping once. Split with fork (don't cut) for best texture.

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.
