A single fry in hot oil split the history of food into “before” and “after” — and it happened in a shed in the backyard of a residential house.
In the city of Ikeda, Osaka Prefecture, there is a neighborhood that still looks perfectly ordinary today: low-rise buildings, narrow lanes, bicycles by the fences. It was here that Momofuku Ando — a Taiwanese immigrant, a businessman with several failed ventures behind him — set up a workshop in his backyard in 1957 and began an experiment to which he gave exactly one year. The goal was stated simply: make noodles that could be stored for months at room temperature and prepared in minutes with nothing but boiling water. By the end of the fifties, postwar Japan was no longer starving, but food logistics remained fragile. Fresh noodles — udon, soba, ramen — spoiled quickly, required refrigeration or immediate consumption. Ando, who was forty-seven, was neither a chemist nor a food engineer; he worked by trial and error, and most early attempts ended in failure — the dough crumbled, soaked unevenly, lost its flavor.
The central question around which that entire year revolved sounds dry and technical, but behind it lies a real puzzle: how do you remove water from noodles so that, when water is added back, they return to their original state? Air-drying produced a dense, glassy product — boiling water struggled to penetrate it, and the noodles remained hard or turned mushy on the outside while staying raw at the core. Ando tried dozens of drying methods before stumbling upon a solution that was, in essence, right in front of him — in any Japanese kitchen where tempura is fried in boiling oil.
The method that Nissin Foods would later call “flash-frying” is simpler than it looks, but its effect is counterintuitive. The noodles are first kneaded, rolled out, cut, cooked, and seasoned. The finished strands are placed into a mold — the future brick — and immersed in oil heated to roughly 150–160 °C. At that temperature, the water inside the dough instantly boils and bursts outward as steam. Every bubble of steam leaves behind a channel, a cavity, a micropore. In a couple of minutes of frying, the noodles’ moisture content drops from roughly 30–40% to 3–5%, and the brick’s internal structure turns into something like a hardened sponge.
That sponginess is the whole trick. When you pour boiling water over the brick, the hot water rushes into the pores through the very same channels the steam carved during frying — only in reverse. The noodles swell, the starch rehydrates, and after about two minutes you get a texture close to freshly cooked noodles. Simple air-drying cannot produce this effect: without pores, water enters the noodles only from the surface, diffusion is slow, and the result is uneven. Frying solved the problem of removing moisture and creating an architecture for its return at the same time — two processes in one technological step. What still fascinates me is that Ando, without laboratory equipment, arrived at this empirically — simply by throwing dough into hot oil again and again, changing the temperature, strand thickness, and immersion time.
Frying had a side benefit: the oil filling some of the pores worked as a preservative. Low moisture suppressed the growth of bacteria and mold, while the oil film slowed the oxidation of starch. The product could sit on a shelf for months — without refrigeration, vacuum packaging, or any of the additives that would appear in the food industry later.
On August 25, 1958, Chicken Ramen went on sale, and this is where the part of the story that is often told wrong begins. The familiar narrative goes like this: cheap food for a poor postwar country, Japan’s answer to hunger. In reality, one package cost 35 yen — roughly six times more expensive than a serving of fresh noodles you could buy at a shop. Chicken Ramen was initially a luxury item, or more precisely, a technological curiosity. Buyers paid for convenience and novelty, not for savings.
The first official sales took place on August 25, 1958, at Osaka Central Wholesale Market, and at first things went badly: wholesalers barely took any stock — in an era when a bundle of udon cost 6 yen, 35 yen cash for a novelty looked like a hopeless proposition. Demand was high not because people could not afford ordinary ramen — but because the idea of “noodles in two minutes without a pot” sounded like science fiction. Essentially, Ando was selling time. A product priced at six fresh servings — and it still took off: word of mouth and television advertising did their work, while distribution was handled from the outset by three major trading houses — Mitsubishi, Itochu, and Toshoku.
The transformation from expensive novelty into a mass-market category took several years and required two things: scaling production up (more volume — lower costs) and the arrival of competitors. By the early sixties, dozens of Japanese companies had begun producing their own versions of instant noodles, using the same frying principle. Competition drove prices down. By the middle of the decade, instant ramen had become what we know it as today: food that costs next to nothing. But that cheapness was the result of market dynamics, not the original idea.
Momofuku Ando did not stop at the brick. In the mid-sixties — Nissin made an inspection trip to the United States in 1966 — he watched how American consumers handled his product and saw something that would have seemed strange to a Japanese person. People broke the brick into pieces, poured the fragments into paper cups, and added boiling water from office coffee makers. They had no bowls, no chopsticks, no habit of eating noodles the Asian way. They adapted the product to their own everyday infrastructure — and Ando noticed.
The result of that observation was Cup Noodles, launched on September 18, 1971. In hindsight, the idea looks obvious: put the noodles into a waterproof cup made of expanded polystyrene, add freeze-dried vegetables and seasonings, seal it with foil. The buyer only has to remove the lid, pour in boiling water, wait three minutes, and eat straight from the cup. No dishes at all. But that “obviousness” is deceptive: Ando had to solve the engineering problem of securing the brick inside the cup so that the noodles did not touch the bottom (otherwise the lower part softened unevenly), and find a wall material capable of withstanding boiling water without deforming or releasing toxic substances.
Cup Noodles removed the final barrier — the need to have any kitchenware at all. The product became fully self-contained: a cup, a fork (in Western versions), a seasoning packet, boiling water from any source. It was food for train stations, construction sites, offices, student dorms, and natural disasters. Sales in Japan were sluggish at first — until Nissin set up on Ginza’s pedestrian street on November 21, 1971, with direct sales and tastings: 20,000 servings sold in four hours. After that, the sales curve went up and never turned back.
At the time of Momofuku Ando’s death in January 2007, global consumption of instant ramen stood at around 86 billion servings a year — and by the end of that same year, according to WINA, demand had exceeded 98 billion. The figure is so enormous that it stops registering as a number and starts functioning as a coordinate: it shows exactly where this product sits on the map of everyday life. Instant noodles are among the most consumed industrial food products on the planet, and a significant share of that volume is still made using the method Ando discovered in his workshop: frying, pores, rehydration.
The technology did not remain unchanged. A new generation of air-drying emerged — so-called “non-fried” noodles — making it possible to reduce calories and fat content. But the classic flash-fried brick retains a dominant share of the market because it is cheaper to produce and delivers that very particular texture to which hundreds of millions of people have grown accustomed. Habit is the currency of the food industry that is hardest to convert.
What amazes me is the scale of its cultural footprint. In South Korea, annual per-capita consumption is among the highest in the world: dozens of packets per person. In Indonesia, Indomie has become so familiar that its name is used as a synonym for food in student slang. In U.S. prisons, instant ramen has become an informal currency, displacing cigarettes. In disaster zones — from earthquakes in Japan to hurricanes in the Caribbean — instant noodles are part of standard humanitarian aid packages. All of it grew out of one technical trick: steam bursts out of the dough, leaving pores behind, and the pores let water back in.
There is a temptation to end the story with a neat arc: a lone inventor, a shed, global domination. But it is more honest to say that Ando hit the intersection of several needs at once — long storage, quick preparation, portability — and found one physical solution for all three. What he did not foresee was the trajectory of the price: a product conceived as premium became a symbol of cheapness. Nor did he foresee that his polystyrene cup would raise environmental questions that Nissin would address decades later, switching to paper containers in 2008 — a year after his death.
I like that there is now a museum in Ikeda devoted to instant ramen, where you can make your own Cup Noodles — choose a cup, draw whatever you want on it, fill it with toppings from several dozen options. Visitors treat it as entertainment. But behind glass stands a reconstruction of that very workshop: a wooden table, a pot of oil, molds for the bricks. The distance between that table and nearly a hundred billion servings a year is one physical principle, applied correctly.
