“I want bread at 9 am Saturday.” Get every step — feed, mix, bulk, shape, proof, bake — with a time, and add it all to your calendar.
Updated · How we source our numbers
Work backwards from when you want the bread. A 1:5:5 starter feed peaks in about 8–14 hours at room temperature. Bulk, shape, proof and bake follow your recipe’s own times.
Tell it when you want the bread ready, and it works backwards through every stage: cooling, baking, preheating, proofing, shaping and bulk fermentation. For sourdough, it also says when to feed the starter so it peaks just as you mix. The result is a dated timeline you can add to your calendar with a reminder at each step.
Only one number in the plan is ours: how long the starter takes to peak. It comes from our feeding ratio chart, checked against King Arthur Baking’s feeding-ratio trial, and your kitchen temperature decides whether the plan uses the fast, middle or slow end of that window. Bulk, proof, bake and preheat times are yours, from your recipe — they depend on your flour, dough temperature and oven, so we don’t pretend to know them. Get the dough to the right temperature with the desired dough temperature calculator.
Need the recipe itself? The sourdough calculator gives exact grams, and the starter calculator works out the feed.
