Quick guide
How to use this calculator
- Choose the complete example closest to your recipe or production task.
- Replace every example value using one consistent measurement and unit convention.
- Review the component results before committing ingredients, cookware or serving quantities.
Calculation method
Transparent kitchen calculation
Build weight = retained starter + feed flour + feed water.
Only the displayed quantities are used. No ingredient density, cooking loss, food-safety threshold or equipment capacity is silently assumed.
Worked example
Three complete starting scenarios
Sourdough Starter Feeding: Build with equal flour and water feeds.
Build weight = retained starter + feed flour + feed water.
Supported inputs
Precision and limits
Kitchen boundary
This is kitchen planning arithmetic. It does not infer food safety, nutrition, allergies, doneness, storage life, commercial compliance or a medically appropriate serving.
Measurements
Ingredient density, packing, moisture, temperature and preparation technique can materially change real quantities.
Food safety
Use authoritative recipe instructions and a suitable food thermometer where safety or doneness matters. Time arithmetic alone cannot establish safety.
Privacy
