Starters fail from forgotten feedings, not bad luck. This log book gives your starter a permanent record: 100 feeding log entries and 25 bake log entries, each with the same fixed fields every time, so patterns are easy to spot.

Feeding logs track date, time, flour type and grams, water grams, room temperature, discard amount, rise, and observations. Bake logs add water temperature, ferment and proof times, bake details, and 1-to-5 taste and texture ratings. A starter origin page records your starter's name, birth date, and feeding schedule up front.

The quick reference covers feeding ratios (1:1:1, 1:2:2, 1:5:5) in plain terms, troubleshooting fixes hooch, no-rise, and sluggish starters, and three discard recipes (pancakes, crackers, flatbread) put the discard to work.
