Tartine Book No. 3 extended Robertson's sourdough philosophy into ancient and heritage grains — einkorn, emmer, spelt, khorasan (Kamut), rye, and buckwheat — documenting their different protein structures, hydration requirements, and fermentation behaviours. The central finding: ancient grains have different gluten structures from modern wheat and require adjusted techniques to produce good bread.
A framework for working with heritage and ancient grains — each with different protein content, gluten structure, hydration requirements, and fermentation behaviour than modern bread wheat.
