Start Here • The Oven-Light Proofing Box, Explained • Your Recipe Didn't Change, Your Kitchen Did 2) HOOK SUMMARY Your sourdough recipe did not change this winter. Your kitchen did. Maya Chen explains what happened when her kitchen dropped to about 17°C, and the two simple changes that got her starter moving again. 3) SHOW NOTES Small Batch Baker episode 42 is a solo episode about a winter problem many home bakers know: a starter that suddenly slows down and loaves that come out flat. Host Maya Chen explains what changed when her kitchen dropped to about 17°C, and why the recipe was never the problem. She shares how she moved from one feeding a day to two feedings with warm water, and how she turned her oven, with only the light on, into a simple proofing box that she checks with a cheap thermometer. The temperature inside the oven was not measured on air, so treat it as STAT_PLACEHOLDER until you check your own. In the second half, Maya answers a listener question about rye flour starters, then closes with a short recap. You will hear: • Why a colder kitchen can slow a sourdough starter • How Maya changed her feeding routine for a cool room • How to set up an oven-light proofing box • Maya's answer to a listener question about rye flour starters Maya's free starter feeding chart is on the show website: FILL_WITH_SPEC 4) KEY TAKEAWAYS • When the kitchen drops to about 17°C, a starter can slow down even if the recipe stays the same. • Feeding twice a day with warm water, instead of once, helped Maya's starter in the cold. • An oven with only the light on can work as a simple proofing box. • A cheap thermometer lets you check the proofing box instead of guessing. • "Your recipe didn't change, your kitchen did" — check the room before you rewrite the recipe. 5) CHAPTER TIMESTAMPS 00:00 Intro and listener mail 02:10 The kitchen drops to about 17°C 06:30 Feeding twice a day with warm water 11:45 The oven-light proofing box 17:20 Listener question: rye flour starters 21:40 Wrap-up 6) GUEST BIO Solo episode — no guest bio.
