From 'Delicious in Dungeon' to Global Menus: the Evolution of Japanese Food Culture

Understand the full story behind From 'Delicious in Dungeon' to Global Menus: the Evolution of Japanese Food Culture with our latest coverage.

To talk about Japanese food requires addressing the umami taste profile, the savory fifth taste identified in 1908 by chemist Kikunae Ikeda. Umami arises primarily from glutamates and nucleotides found in ingredients like dried bonito flakes, aged miso, shiitake mushrooms, and ripe tomatoes. Unlike sweetness or acidity, which present themselves immediately on the palate, umami provides a lingering, tongue-coating depth that anchors other seasonings.

Japanese culinary slang and gourmet vocabulary describe food sensations with pinpoint specificity. Textural descriptors, collectively referred to as shokkan, dominate conversation at the table. A crispy croquette is saku-saku; a silken tofu is tsuru-tsuru; a chewy mochi or udon noodle is mochi-mochi. Food critics rarely stop at declaring that a dish tastes good. They measure its koku, a term encompassing richness, complexity, and lingering body.

When a dish reaches exceptional quality, Japanese speakers turn to vivid idioms. The most famous is hoppe ga ochiru, which translates literally to "my cheeks are falling off." The imagery evokes the physical sensation of facial muscles relaxing completely under the influence of intensely delicious, savory food.
