I’ve been making sushi for 38 years, and I’m still learning. You have to consider the size and color of the ingredients, how much salt and vinegar to use and how the seasons affect the fattiness of the fish.

Morimoto frames sushi as a lifelong discipline rather than a skill one “finishes.” The remark stresses that mastery in traditional crafts is measured by sustained attention to variables that outsiders may overlook: visual harmony (size and color), precise seasoning (salt and vinegar), and the natural fluctuations of ingredients (seasonal fat content in fish). The quote also implies humility as a professional ethic—experience deepens awareness of complexity instead of producing complacency. In a broader culinary context, it highlights an artisanal worldview in which technique, ingredient quality, and seasonality are inseparable, and where learning is continuous because nature and materials are never identical from day to day.
