Where the free site ends, these go further.
Recipes, glossaries, and chapter PDFs stay free. The pieces below are the ones built for repeated use — notebooks you carry to the stove, audio you play while you cook, frameworks you re-read.
The Fermentation Notebook
The failure-decision manual for home fermentation.
Salt in grams, temperature in °C, and the discard rules that make years of home fermentation safe. Sauerkraut, shio-koji, miso, vinegar pickle, kombucha, nukazuke — each with the cues that decide wait / adjust / refrigerate / discard, and the §SD-1 through §SD-8 doctrine that Chapter 5's failure catalog cites by label.

All 11 chapters bound into a single A4 PDF (~180 pages EN / ~260 pages JA). Title page, table of contents, every chapter in sequence. Same content as the free chapters at /free — bound into one file you can keep, gift, or print.
