旨味の重層 (Umami no Jūsō): Layered Umami Construction
I
Origin
Japanese professional culinary education teaches umami not as a single flavour to be added but as a layered construction — each layer contributing different compounds (glutamates, inosinates, guanylates) that synergise to produce a depth greater than any single source. This framework, developed in Japanese professional kitchens and culinary schools, is more systematically articulated than in any other culinary tradition.

Description
