Separate Flour and Water Already Present in a Sourdough Starter

Adding starter changes both sides of a dough's hydration fraction. Count the flour inside it as well as its water before adjusting a family recipe, especially when changing between stiff and equal-flour-and-water preferments.

1 · Component code | starter, flour or water | grams | starter hydration (%)

HYPOTHESIS / PROTOTYPE — checkout unavailable. Calculation is local. A draft is saved automatically in this browser profile when storage is available; Reset to sample clears it. Optional Pro history stores only five summaries and has its own deletion control. State links encode your inputs and can remain in browser history, clipboard or recipients’ records; share only non-sensitive rows. Optional external AI formatting leaves this device. The required site analytics beacon reports page activity; shared URLs contain encoded inputs. Do not treat an encoded URL as private. The calculator has no input-collection endpoint.

Data note: The preferment-balance chart processes Component code | starter, flour or water | grams | starter hydration (%) locally. Starter/sample selection and Run compute in this tab; no input is sent by the calculator. A local draft may be saved; explicit state-link sharing or optional external AI formatting can disclose inputs. Use non-sensitive labels.

Perspective: Before: starter mass disappeared into an uncertain hydration estimate. After: its flour and water are explicit components of the recipe's denominator.

Recipe mass-balance planning only, not fermentation, allergy or food-safety guidance. Confirm uncertain starter composition with a knowledgeable baker and follow an established recipe and food-handling instructions; do not attempt to remove calculated water from mixed dough.

Optional filing controls are a local prototype.

Before using the preferment-balance chart

Hydration here means water mass divided by flour mass, multiplied by 100. It does not mean water as a percentage of total dough mass. A starter's hydration must be known from its recipe or a verified feeding record; age, appearance and total mass do not reveal it. Use only flour, water and starters whose mass can be modeled entirely as flour plus water. Milk, eggs, oils, sweeteners and other ingredients contain components this model does not decompose. Flour and water rows use a zero in the fourth cell to state that no starter hydration applies. A positive final flour mass is required. The target is your chosen recipe assumption, not a universal bread recommendation, and the adjustment is calculated for an unmixed plan.

Optional AI formatting, never the calculation

Manual entry completes this preferment-balance chart for free without signup. If available to you, the free AI Studio interface linked in the sources may format fictional or non-sensitive notes; external access may require an account. No API key or AI call is built into this tool. Free-tier content may be used to improve products. Review each cell and transcribe it to the labeled row schema; do not paste the JSON object into the row box.

Format only these fictional or non-sensitive notes for a preferment-balance chart. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string", "string"]}], "setting": "string"}. The columns are Component code | starter, flour or water | grams | starter hydration (%); the setting is Chosen final flour-basis hydration (%). Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.

An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
