The Starter Jar

How to Revive a Neglected Starter Left your starter in the fridge for weeks (or months)? Don't throw it out — here's how to bring it back to life. Sourdough starters are surprisingly resilient. Assessing viability: Smell — strong funky odor (acetone, alcohol, cheesy) is normal. If you detect mold or something rotten, discard and start fresh. Look — hooch (dark liquid on top) is harmless alcohol from the yeast, a sign it's hungry not dead. Look for mold (fuzzy discolored patches — pink, orange, green, black). If mold present, discard. Texture — very stiff and dense is normal after long storage. Keep a small insurance portion of active starter in the freezer. Revival schedule: Day 1 — discard all but 1 tablespoon, combine with 50g unbleached all-purpose flour and 50g lukewarm water (85°F/29°C), mix well until no dry flour remains, cover loosely, leave at room temperature (70–75°F/21–24°C). Day 2 — discard all but 1 tablespoon, feed again with 50g flour and 50g lukewarm water, mix well, cover, leave at room temperature. Days 3–7 or longer — continue discarding all but 1 tablespoon and feeding every 12–24 hours, watch for bubbles, slight rise, and more pleasant tangy smell, increase to every 12 hours as activity builds. Ready when doubling within 4–8 hours of feeding. Troubleshooting: not showing activity — try warmer water (85–90°F), warmer room, or whole wheat or rye flour for more nutrients. Too sour — feed more frequently (every 8–12 hours) with higher flour-to-starter ratio. Weak starter — continue feeding regularly. Be patient — reviving a neglected starter can take time.
