Split Schedule: Bulk Today, Shape Tomorrow

A split schedule bulks dough partially, refrigerates overnight in the bowl, then shapes and proofs the next day — useful when you can't shape the same evening.

How to do it

1. Mix and fold through early strength.
2. Let bulk reach roughly halfway cues (some rise, some bubbles).
3. Cold bulk overnight.
4. Next day: warm slightly if rock-hard, finish bulk if needed, shape, final proof, bake.

Tradeoffs

Flavor can be excellent. Shaping gassy cold-bulk dough takes a gentle hand. If dough overferments in the fridge, pivot to focaccia.

Buffer strategies

Build buffers into the stages that tolerate cold: shaped final proof and, carefully, bulk. The fridge is a pause button, not a punishment. If life interrupts, chill earlier while dough still has strength.

Adapting the template

Treat every timetable as a draft for ~72–75°F. Shift earlier in summer, later in winter, and always confirm with dough feel. Your best schedule is the one you can repeat on a normal week.

One thing to remember

If you only remember one number, remember dough temperature — it explains more "mystery" outcomes than flour brand lore.

Constraint first

Write the immovable appointments (work, school, sleep) then place mix/shape/bake in the gaps. Dough should orbit your life, not colonize it.

Starter logistics

A fridge starter plus two wake-up feeds beats trying to keep a counter culture perfect during a chaotic week.

Field notes

Treat this topic as a checkpoint inside a full bake, not a standalone trick that overrides fermentation. If results swing wildly, stabilize feeding and room temperature for a week so you can see the signal again. Keep salt around 2%, know your dough temperature, and judge readiness with rise and feel before you invent exotic fixes. A schedule you can keep beats a perfect schedule you abandon on Thursday.

Also useful: weigh everything, preheat longer than you think, and cool fully before you judge crumb quality. Those three habits make every other tip more reliable.

Frequently asked questions

Vs shaped cold proof?

Shaped retard is simpler for scoring from cold; cold bulk is better when shaping time is the bottleneck.

How long cold bulk?

8–16 hours common; longer increases risk.

Covering?

Yes, tightly enough to prevent skinning.
