Sourdough Baker's Toolkit: Recipe Calculator, Bake Schedule Planner, Bake Log & Starter Tracker + Printable Guide

Stop doing baker's-percentage maths on your phone and guessing when to start your levain. This toolkit does the numbers and the scheduling so you can focus on the bread.

What's inside the spreadsheet (Excel, Google Sheets, Numbers):

• Recipe Calculator: choose the number of loaves, loaf weight, hydration, starter %, salt and flour blend, and get exact grams AND ounces for every ingredient. It counts the flour and water inside your starter automatically, shows true baker's percentages, and tells you exactly what to mix for your levain.
• Recipe Converter: paste in any recipe and instantly see its hydration, starter % and salt %.
• Bake Schedule Planner: tell it when you want fresh bread and how warm your kitchen is. It works backwards to build your full timeline (levain, autolyse, mix, stretch & folds, shaping, cold or room-temperature proof, preheat, bake and cool), flags any middle-of-the-night steps, and tells you what water temperature to use.
• Bake Log: record every loaf and rate it 1–5. It finds your best bake and the hydration that works best for you.
• Starter Tracker: a feeding calculator plus a feed log that works out hours-to-peak and gives your starter a health check.

Plus a 9-page printable Baker's Guide & Logbook:

• Baker's percentages made simple, with a worked example
• Temperature and timing guide, and oven and weight conversions
• A troubleshooting chart for 12 common problems: flat loaves, dense or gummy crumb, no ear, too sour, sluggish starter and more
• Starter care guide
• Printable bake log cards and a starter feeding chart

You get the blank toolkit, a filled example so you can see how it all works, and the printable guide (one .zip download).

Perfect for new and experienced sourdough bakers, and a lovely gift tucked in with a jar of starter.

Timings are estimates; every starter and kitchen is different, so watch the dough, not just the clock.
