From a Grain of Rice to an Ocean: The Epic Story of the 3,000-Year Evolution of Sushi Ingredients
I. Early to Mid-Edo Period: From the 17th century to the early 19th century, sushi was prevalent. The refinement and regionalization of ingredients were well established.
After the Tokugawa shogunate unified Japan, a period of nearly two hundred years of peace ensued, and the commodity economy developed rapidly. The three major cities of Osaka, Kyoto, and Edo rose, and Japanese culinary culture experienced unprecedented prosperity. The sushi ingredients entered a period of refinement and regionalization.
The most mainstream form of sushi during this period was the "Kai Sushi" in the Kansai region - the chefs poured the seasoned rice into a wooden mold, placed the prepared ingredients on top, pressed it down, and cut it into cubes for easy carrying and consumption. The development of sushi ingredients also witnessed three key breakthroughs:
First, the recipe for vinegar rice was fully established. The chefs no longer relied on natural fermentation to obtain the sour taste, but instead used a fixed proportion of core ingredients such as rice vinegar, salt, and sugar to prepare the vinegar rice. The temperature, acidity, and viscosity of the rice had clear standards, and the basic recipe for modern sushi rice was thus completely determined, with no essential changes occurring.
Second, nori officially became the core ingredient of sushi. In the early Edo period, the artificial cultivation technology of kelp in the Seto Inland Sea matured, and the wild kelp that could only be collected on the rocky shores of the coast became a large-scale production ingredient. After baking, the nori has a crispy texture and a rich seafood aroma, which can be used to wrap vinegar rice and ingredients to make roll sushi, can be used to fix the shape of sushi, and can add flavor to the ingredients, quickly becoming an indispensable part of sushi. Roll sushi forms such as Tairo, Shichirai, and Riri also emerged with the popularization of nori. Pickled radish, cucumber, and dried scallops, etc., also became fixed ingredients for roll sushi.
Third, the regionalization of ingredients and the pre-processing system matured. The sushi chefs in the Kansai region still adhered to the principle of "preparing ingredients for seasoning in advance", and almost never used completely raw fish to make sushi. Mackerel would be pickled with rice vinegar to remove the fishy smell, starfish would be slow-cooked with sauce to absorb the flavor, shrimp would be scalded in advance to shape, octopus would be repeatedly pounded to achieve a soft and tender texture, and shellfish would be lightly boiled in salt water to enhance the flavor. Different regions also formed their own sushi ingredients: the box sushi in Kyoto preferred wild mackerel from the Danor Peninsula, the roll sushi in Osaka focused on mackerel and octopus from the Seto Inland Sea, and the sushi restaurants along the Seto Inland Sea coast featured local oysters and prawns. Even the classic sushi ingredient, sweet egg roll (sweet omelette), was officially established during this period and became an indispensable vegetarian ingredient in sushi.
II. The End of the Edo Period: 1820s - 1868, The Birth of Preparatory Sushi - The Final Forming of the Modern Sushi Ingredient System
In the Edo period of the 19th century, Edo had become a super metropolis with a population of over one million. The city was filled with porters, artisans, traders, and citizens, who needed cheap, fast-serving, and bite-sized street food. It was precisely this era's demand that gave rise to the now-familiar "hand-held sushi" and completed the final shaping of the sushi ingredient system.
In 1824, the renowned "God of Hand-held Sushi" Hattori and Katsuo opened a sushi stall by the Nishi-Kanda Bridge in Edo. He completely broke the traditional Kansai sushi practice of pre-seasoning and pressing for shape, and pioneered the "hand-held sushi" model of "making and eating immediately". The core of this model was the unique resources of the Edo Bay (now Tokyo Bay) - at that time, the water quality of the Edo Bay was clear, with abundant plankton, and was called "Edo Before". The fresh catches from the sea in the morning could be delivered to the sushi stall by noon, with the ultimate freshness allowing the chefs to finally abandon the pre-treatment of fermentation, salting, and cooking, and directly use raw fish slices with rice vinegar to make sushi.
During this period, the classification system of sushi ingredients was completely formed and is still used by sushi restaurants worldwide to this day:
White-fleshed fish: With redolent fish like red snapper, halibut, and sole as the core, they have firm and refreshing flesh, low fat content, and a sweet taste. They are the classic basic dish of hand-held sushi and the category that most tests the freshness of the ingredients;
Red-fleshed fish: With tuna (mackerel) as the core, it has undergone a transformation from "inferior fish" to "sushi king". Previously in Japan, tuna was considered an inferior fish due to its high fat content and was regarded as something only the poor could afford. The extremely fresh tuna in Edo Before allowed the chefs to discover the rich, soft middle belly, and plump belly of tuna, and from then on, tuna became the top ingredient in the sushi world;
Light fish: Represented by mackerel, summer flounder, bamboo perch, and sardines, with high fat content and a strong fishy flavor. Chefs would use rice vinegar for a short period of time to marinate, which could not only remove the fishy smell but also stimulate the freshness and sweetness of the fish meat, becoming a classic category of hand-held sushi;
Cooked shellfish: Maintaining the pre-treatment tradition of Kansai sushi, with slow-cooked starfish, yuba, repeatedly pounded cooked octopus, and fresh red shellfish, Arctic shellfish, and sail shellfish as the core, it has rich and intense flavors;
Wasabi and soy sauce: Officially became the fixed accompaniments of sushi. Freshly ground wasabi not only adds a spicy flavor to sushi but also has the function of sterilization and disinfection, perfectly adapting to the consumption needs of raw fish slices; while brewed soy sauce became the core seasoning of sushi, and chefs would brush the soy sauce on the sushi in advance or let diners dip and eat it, completely establishing the modern sushi seasoning system.
III. Meiji - Showa Era: 1868 - 1980s, The Cold Chain Revolution, Globalization and Popularization of Sushi Ingredients
The initiation of the Meiji Restoration allowed Japan to completely open its doors to the outside world, with Western industrial technologies and dietary cultures flooding into Japan. Sushi ingredients underwent a second revolutionary transformation - the advent and popularization of cold chain technology.The emergence of refrigerators, refrigerated trucks, and refrigerated ships completely broke the geographical restrictions on sushi ingredients. Previously, sushi restaurants could only use local catch from the day, but with the maturity of cold chain technology, king crab from Hokkaido, summer flounder from the Sea of Okhotsk, tuna from Kyushu and Kagoshima, and sea urchin from the Japanese Sea could all be transported to sushi restaurants across Japan while maintaining the ultimate freshness. The selection of sushi ingredients suddenly shifted from "local limitation" to "nationwide availability".At the same time, Western dietary culture also profoundly influenced the development of sushi ingredients. In the Meiji era, the Japanese government encouraged the consumption of red meats such as beef and pork, and innovative categories such as beef sushi and pork sushi emerged; and after World War II, with the entry of US troops into Japan, processed ingredients such as luncheon meat, crab sticks, and mayonnaise also began to enter the sushi recipe list, laying the groundwork for the subsequent globalization and integration of sushi.During this period, the most legendary ingredient transformation was the birth of salmon sushi. Many people are unaware that salmon is not a traditional sushi ingredient in Japan - the Pacific salmon native to Japan mostly has parasite risks and can only be cooked and eaten, and is never used for raw fish sushi. It was not until the 1980s that Norwegian fishery companies, in order to open the Japanese seafood market, introduced their own artificially farmed, parasite-free Atlantic salmon to Japan. After a decade of promotion, the Japanese finally accepted salmon sushi. The rich fat, tender texture, and affordable price made salmon sushi quickly become popular in Japan and eventually became the most popular sushi category in the world, without a doubt.
IV. Heisei - Reiwa Era: From 1990 to the present, global integration, the endless possibilities of sushi ingredients
In the 1960s, sushi was introduced to the United States along with Japanese immigrants, but on the other side of the Pacific Ocean, it underwent a completely new transformation. Japanese sushi chefs in California, in order to adapt to the dietary habits of Americans who do not like raw fish and do not like seaweed, invented the famous "California Roll": seaweed is wrapped inside, rice is wrapped outside, and avocado, crab meat sticks, cucumber are filled inside, and fish roe is sprinkled on top.This was the first time that sushi ingredients completely broke away from the traditional framework of Japan. This avocado, which has no connection with Japanese cuisine, thus became a classic ingredient of sushi and also ushered in the era of global integration of sushi ingredients. In the following decades, sushi swept the world, colliding with local culinary cultures in different countries and regions, giving birth to countless new ingredient combinations:The Philadelphia Roll in the United States added cream cheese and smoked salmon, becoming the representative of American sushi;The seaweed rice roll in Korea added kimchi, Korean chili sauce, and luncheon meat, forming a unique Korean sushi system;Sushi restaurants in China added local ingredients such as fried dough sticks, meat powder, salted egg yolks, and spicy strips to sushi, creating sushi categories that suit the taste of the Chinese population;Even in Southeast Asia, Europe, and Australia, fruits such as mango, strawberry, and durian, and ingredients such as cheese, bacon, and fried chicken, have also entered the list of sushi ingredients, creating countless creative sushi.At the same time, the maturity of cold chain logistics and global trade has infinitely expanded the boundaries of sushi ingredients. Today, any high-end sushi restaurant in the world can enjoy Spanish bluefin tuna, New Zealand king salmon, Canadian Arctic cod, Russian sea urchin, and French oysters. The boundaries of sushi ingredients have changed from "limited to Edo Prefecture" to "shared global produce".
