Description
Medieval mortrew stews and marchpane pastries use clay heat‑mass and Maillard chemistry to develop depth of flavor and texture.
Technical
Mortrew vessels, fired clay with ~2 kg thermal mass, are pre‑heated to ~120 °C to prevent shock; prolonged boiling at ~100 °C extracts glutamates while iron leaching lowers pH to ~5.5, enhancing umami. Marchpane dough (almond flour:sugar 1:1, 10 % egg whites) undergoes Maillard reactions between almond proteins and sugars around 140 °C, forming melanoidins and caramelized crust, while sugar crystallization solidifies the interior.
