About Starter Care Lab
Honest, practical starter care
Starter Care Lab is an English-language publication for home bakers who want to keep their sourdough starters healthy. We explain feeding, temperature, storage, and recovery in plain terms, with measurements in grams, Celsius, and Fahrenheit.
The guidance here is written for realistic home kitchens. Nothing is guaranteed, and every starter behaves a little differently, so we encourage noting what you observe and changing one thing at a time.
