PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Medieval European mustard making relied on enzymatic conversion of glucosinolates to isothiocyanates during seed grinding and low‑temperature soaking, followed by ambient aging to develop flavor.
Origin: English and French medieval societies (14th–15th centuries) — England and France
See full technique reference →During grinding, the enzyme myrosinase hydrolyzes glucosinolates in mustard seeds to produce pungent isothiocyanates. Low‑temperature soaking (15–20 °C) activates myrosinase and leaches water‑soluble glucosinolates, while subsequent 2–3 week aging at ~20 °C allows secondary fermentation and flavor maturation.
