Field notes
The site combines a decision tree with practical fermentation references. Its checker asks about surface appearance, smell, and brine coverage, while the calculator converts ingredient weight into salt amounts for several ferment types. The page also includes a day-by-day visual sequence around 20 °C and identifies the project as a one-person kitchen business in Poland. A paid book expands the material with twenty recipes and additional daily guidance.
