Sourdough bake day planner

Choose when you want to mix your dough. The planner works backwards to when to feed your starter so it peaks right then.

• The times are for an active starter kept at room temperature. Straight from the fridge it's too sluggish: start feeding it regularly about two days before you bake.
• The times come from King Arthur Baking's tests at about 78°F (26°C): 1:1:1 peaked in about 4 to 6 hours, 1:2:2 by 8 hours and 1:4:4 by 12 hours. Warmer is faster and cooler is slower.
• Check the jar about 30 minutes before you mix. Your starter should have about doubled.
• In Sourdough Starter Tracker, Plan a bake reminds you when to feed and when to check the jar, moves the rest of the plan if you feed late, and also plans the wake-up feedings for a starter kept in the fridge.
