Sushi originated in Southeast Asia as a survival technique to prevent fish from rotting in tropical heat. In its earliest form, known as narezushi, fish was packed with salt and rice to ferment for up to a year. During this era, the rice was used strictly as a preservation medium—acting like a "biological refrigerator"— and was discarded, while only the fermented "pickled" fish was consumed.
The evolution toward modern sushi was driven by a desire for convenience and speed. During the Muromachi period, people grew impatient and began eating the fish while it was only partially fermented (namanare), allowing them to eat the rice while it still had texture. Later, in the 17th century, Matsumoto Yoshiichi introduced the use of rice vinegar to mimic the sour taste of fermentation instantly. This "quick sushi" or haya-zushi reduced preparation time from weeks to hours, eventually leading to Hanaya Yohei’s invention of hand-pressed nigiri-zushi in the 1800s.
While many consumers associate sushi with never-frozen fish, modern safety regulations in many countries, including the U.S., mandate that fish intended for raw consumption be "flash-frozen." This process involves freezing the fish at extremely low temperatures, such as minus 35 degrees Celsius, to kill potential parasites. Advanced technology allows this to happen so quickly that the cell structure of the fish is preserved, maintaining the texture and flavor of the meat.
The concept of shun refers to the exact moment an ingredient is at its absolute peak of flavor, texture, and nutritional value. This philosophy is deeply rooted in the Japanese calendar, which recognizes dozens of micro-seasons lasting only a few days each. A master sushi chef tracks three phases of an ingredient: hashiri (the early, delicate start of the season), shun (the peak), and nagori (the lingering, deeper flavors at the end of the season), ensuring the meal reflects a specific moment in time.
According to traditional etiquette, nigiri can be eaten with your hands to better feel the temperature and preserve the delicate structure of the rice. When using soy sauce, you should turn the piece upside down and dip only the fish, as the rice acts like a sponge and will fall apart if soaked. Additionally, wasabi should not be mixed into the soy sauce, and the pickled ginger (gari) should be eaten between different types of fish as a palate cleanser rather than as a topping.
