SOURDOUGH BREAD

the timeline, hydration and grams — per King Arthur Baking’s Naturally Leavened Sourdough Bread

Built as a memo rather than a table: the thing worth hanging it up for reads across the room, with the full reference in smaller type below it.

Three sizes in one archive — from a sheet on the fridge to a poster on the wall.

Formats: A4 · A3 · A2
What you get: Print-ready PDFs, one per size, with every letterform converted to outlines — nothing to install, nothing to shift.
Subject: food · everyone · memo · kitchen

Grams, minutes and the oven setting are verbatim from King Arthur Baking’s “Naturally Leavened Sourdough Bread” (kingarthurbaking.com); the starter’s 100 % hydration is from their “Sourdough Starter” (fed 50 g + 50 g). The band is proportional to the minutes; marks below it are hand work, untimed in the recipe. 232 °C is computed from 450 °F. Checked 2026-08-13.

THE STARTER IS FLOUR AND WATER TOO

Count hydration from the poured water alone and you get 58 %. But 454 grams of starter fed equal weights of flour and water hide another 227 grams of each. That makes 624 g of water to 912 g of flour — 68 %, and the dough behaves exactly those ten points wetter than the naive count promises.

Sourdough recipes only compare after this recalculation — both percentages on this sheet are derived from the same grams by the build check.

Colour carries meaning, but meaning never rests on colour alone — the sheet reads in black and white.
Nothing about how it was made: the sheet carries only what the reader needs.

Printing

Three sizes in the archive: A4 — 210×297 mm, A3 — 297×420 mm, A2 — 420×594 mm.
All text is converted to outlines. No fonts to install, and nothing shifts on another machine.
White background and sparing fills — it prints on a home printer without draining the cartridge.
Margins of at least 10 mm: a home printer cannot print to the edge.
No stroke thinner than 0.3 mm, so nothing disappears in print.

Why the numbers can be trusted. Every countable number here is computed from data rather than typed in, and the sheet must pass 8 independent checks before it is allowed to build — how many items there are, the order they come in, and the claim in the highlighted box itself. If one fails, there is no file.
