DAY 14 — Maturity Check

DAY 14 — Maturity Check

Your starter should now triple in size within 4–6 hours of feeding. That's the benchmark for maturity.

The float test (optional but useful): Drop a small spoonful of peak starter into a glass of room-temperature water. If it floats, it's gas-rich and ready to bake with. If it sinks, give it another day or two of feeds.

When the starter passes the triple test consistently, you're ready to bake.


PHASE 2 — BAKE DAY (≈ 24-Hour Process)

This phase has two clock rhythms: an active afternoon (~5 hours of work spread across 8 hours) and a long overnight cold proof, then a morning bake. Plan accordingly.

Note: All times are illustrative. Adjust based on your kitchen temperature — warmer rooms speed everything up, cooler rooms slow it down.
