About "Corn Tofu (Morokoshi Tofu)"
Corn Tofu (Morokoshi Tofu) made using standard canned corn. The corn is blended, mixed with potato starch, cooked until thick, and chilled to set into a tofu-like texture. A vibrant green sauce combining white miso and aoyose (a natural green coloring made from spinach) adds beautiful color, highlighting the corn's natural sweetness and chewy texture.

How to Make "Corn Tofu (Morokoshi Tofu)"
- 1
Drain the corn
Drain the canned corn thoroughly using a strainer to remove excess moisture.
- 2
Blend the corn
Place the drained corn in a blender and blend until finely pureed into a juice-like consistency.
- 3
Add potato starch and mix
Add potato starch (about 20% of the corn's weight) and blend again until it becomes a smooth paste.
- 4
Cook and knead in a pot
Transfer the corn paste to a pot and cook, stirring vigorously from the bottom with a wooden spatula. Continue until the mixture becomes highly viscous and sticky. Pay close attention to prevent it from burning.
- 5
Pour into a mold and chill to set
Once thoroughly cooked and thickened, transfer to a mold (or tray) and smooth the surface. Submerge the mold in ice water, cover with plastic wrap, and place plenty of crushed ice on top to chill and set completely.
- 6
Make the aoyose
Finely chop raw spinach leaves, place them in a blender with a small amount of water, and blend into a green juice. Strain through a sieve to extract only the liquid, then heat it in a pot. Bring to a boil, skim off the green chlorophyll that floats to the surface, cool it in ice water, and strain/squeeze through a paper towel to complete the flavorless, pure green paste called 'aoyose'.
- 7
Make the kinome miso sauce
Place white miso and fresh kinome (sansho leaves) in a blender, add the prepared aoyose, and blend. Gradually add cold dashi stock while blending to adjust the consistency into a smooth, moderately thick sauce.
- 8
Plate and serve
Remove the chilled and set corn tofu from the mold, carefully slice it with a knife, and arrange on a plate. Generously spoon the vibrant green kinome miso sauce over the top.
Food Science
The rich sweetness of the corn combines with the umami components (glutamic acid and inosinic acid) of the dashi and white miso, creating a synergistic flavor effect. Additionally, heating and gelatinizing the starch in the potato starch traps moisture, providing precise water control that results in a chewy and smooth tofu texture. Furthermore, the refreshing aroma and subtle bitterness of the kinome leaves balance the sweetness and umami, rounding out the overall flavor profile of the dish.

The 3-Year Milestone and a Message to the Youth
At 95 years old, Iron Chef of Japanese Cuisine Rokusaburo Michiba reflects on his culinary career. When asked by staff at what point he felt he could commit to being a chef, Michiba replies, 'Definitely after three years.' He explains that after three years, you begin to understand the work, and the joy of hearing customers say 'Thank you for the delicious meal' becomes your ultimate driving force. He also wrote the message 'Let's get along' on a calligraphic board for the younger generation. Drawing from his own youth, he shared a warm message that seniors should not just give orders, but understand the feelings of younger staff and treat them as equals rather than superiors and subordinates.
A Lifelong Love for Corn Rooted in Childhood
The featured ingredient for this recipe is canned sweet corn, a convenient household staple. Michiba smiles as he shares his deep love for corn since childhood. He fondly recalls grilling and biting into corn as a child, noting how even just seeing corn growing in a field would excite him. As a familiar ingredient frequently used in summer dishes, it holds a special place in his heart. Today, he uses this humble canned corn to create 'Corn Tofu (Morokoshi Tofu),' showcasing the traditional techniques and creative ideas of an Iron Chef. Anticipation builds as a common household ingredient is transformed into an exquisite Japanese dish through professional mastery.
Blending Corn to Create the Tofu Base
As the first step of cooking, thoroughly drain the canned corn using a strainer. Place the drained corn into a blender (or food processor) and blend until finely pureed into a juice-like consistency. A key point of this dish is adding potato starch at about 20% of the corn's weight. Once the starch is added, blend again to ensure everything is uniformly mixed into a smooth paste. Although the mixture is still quite liquid at this stage, the potato starch will play a crucial role in the upcoming heating process, creating a uniquely chewy texture.
Thickening in a Pot and Chilling to Set
Transfer the corn paste to a pot and heat it. From this point, it is extremely important to stir vigorously from the bottom of the pot using a wooden spatula while taking utmost care to prevent burning. Watching Chef Yamamoto stir the pot with intense focus, the staff remarked in surprise, 'You were really giving it your all.' Once the mixture is thoroughly cooked and becomes highly viscous, transfer it to a mold (tray) and smooth it flat. Next, submerge the mold in ice water, cover with plastic wrap, and pile plenty of crushed ice on top to chill and set it into a tofu shape. Chilling allows the potato starch to firmly set the mixture.
Extracting Green with the Aoyose Method
Next, we perform 'aoyose,' an important technique that determines the visual appeal of the dish. This is a traditional Japanese culinary method for making natural green food coloring from spinach. First, finely chop raw spinach leaves, place them in a blender with a little water, and blend into a green juice. Strain this through a sieve to extract only the liquid, transfer it to a pot, and heat. Bringing it to a boil causes the water and the green chlorophyll of the spinach to separate, with the green matter floating to the top. By skimming off only this floating green component, cooling it in ice water, and squeezing it through a paper towel, you get a flavorless, pure green paste called 'aoyose.'
Vibrant Kinome Miso Sauce with Aoyose
Using the newly made 'aoyose,' we create a vibrant green sauce to add color to the dish. Place white miso and fresh kinome (sansho leaves) in a blender, add the 'aoyose,' and blend. Since it is difficult to get a brilliant green color from kinome alone, adding this natural coloring agent results in a visually stunning, bright green kinome miso. Finally, gradually add cold dashi while blending to thin the mixture into a smooth sauce of the perfect consistency. This sauce creates a beautiful color contrast against the yellow corn tofu.
The Completion of Chewy and Sweet Corn Tofu
Remove the chilled and set corn tofu from the mold, carefully slice it with a knife, and arrange on a plate. Generously spoon the vibrant green kinome miso sauce over it to complete the 'Corn Tofu.' Tasting the dish, Michiba's granddaughter, Natsuki Iijima, was amazed, saying, 'It's more like mochi or warabimochi than tofu—so chewy and soft.' She praised the flavor, noting, 'It's gentle, subtly sweet, and the natural flavor of the ingredients comes through beautifully. Eating the tofu on its own tastes intensely of corn.' Michiba added, 'It might be close to daikon radish cake (daikon mochi).' This dish elevates simple home ingredients into a masterpiece of professional craftsmanship.
