This optimized system for sourdough discard crackers focuses on a low and slow baking approach that prioritizes even dehydration over raw speed, eliminating guesswork to produce a consistent, professional-grade result.
The final bake time is wide (20-50 minutes) because starter viscosity varies. Primary cues for doneness must be visual (deep, golden amber color across the entire sheet) and tactile (center feels firm, not soft). Do not pull them early; pale crackers equal soggy crackers. Allow crackers to cool completely on the baking sheet to maximize crispness before breaking apart. Store cooled crackers in an airtight glass jar away from humidity; never store in the refrigerator. To re-crisp stale crackers, bake at 300°F for 3-5 minutes.
