Key ingredients
Core cooking flow
- 1 Soak 1 kg pork back bones and 500 g pig trotters in cold water for 30 minutes.
- 2 Bring a large pot of water to a boil and blanch the bones and trotters for 10 minutes.
- 3 Put the cleaned bones, trotters, 6 garlic cloves, and 30 g ginger in fresh water.
Classic Tonkotsu Ramen is a Japanese noodle dish defined by its deep, creamy pork bone broth. The foundation of this soup requires boiling pork back bones and pig trotters with garlic and ginger at a continuous, vigorous roll for seven to eight hours. This sustained high heat emulsifies the fat and breaks down the collagen, producing a milky, gelatinous broth that coats the palate. It is served with thin, firm noodles that retain a springy bite without becoming soggy in the heavy soup. Top the bowl with pork belly chashu braised in soy sauce and mirin, soft-boiled eggs marinated in the braising liquid, and sliced green onions. Maintaining a strong boil without reducing the heat is critical to achieving the characteristic white color and rich texture. Prepare the chashu a day in advance and chill it for easier thin slicing.

Soak 1 kg pork back bones and 500 g pig trotters in cold water for 30 minutes.
If the water turns cloudy, change it once to reduce odors before blanching.
- 2Heat
Bring a large pot of water to a boil and blanch the bones and trotters for 10 minutes.
Discard the foamy water, then scrub the pieces under running water so the broth stays clean.
- 3Control
Put the cleaned bones, trotters, 6 garlic cloves, and 30 g ginger in fresh water.
Keep the pot at a vigorous rolling boil over high heat for 7-8 hours so fat and collagen emulsify.
- 4Control
As the broth reduces, add hot water as needed and do not lower the heat to a gentle simmer.
When it turns milky and slightly sticky on the lips, strain out the solids.
- 5Control
Braise 300 g pork belly with 3 tablespoons soy sauce and 2 tablespoons mirin over medium-low heat.
Turn it as it cooks, let it cool, and refrigerate if possible for cleaner thin slices.
- 6Finish
Soft-boil 2 eggs and marinate them in the chashu braising liquid for 2 hours.

Tokyo-Style Shoyu Ramen (Classic Japanese Soy Sauce Chicken Broth Ramen)
Tokyo-style shoyu ramen is considered the closest descendant of the original ramen that appeared in Japan over a century ago. The broth starts with chicken carcasses simmered until the liquid turns a warm amber, then seasoned with kaeshi - a concentrated blend of soy sauce, mirin, and sugar that has been cooked and rested. A thin film of chicken fat floats on the surface, trapping heat and delivering a gentle richness with each spoonful. The noodles are thin and straight, designed to be slurped quickly before they soften, and their wheat flavor stands distinct against the soy-tinged broth. Classic toppings include narutomaki fish cake with its pink spiral, strips of menma, a halved soft-boiled egg, and a sheet of nori. The bowl is intentionally restrained - no heavy pork fat, no thick miso - letting the clarity of the soy-chicken combination speak for itself.
Hakodate Shio Ramen (Hokkaido Clear Salt-Seasoned Chicken Ramen)
Hakodate shio ramen is the oldest style of ramen in Hokkaido, originating from the port city of Hakodate in the south of the island. The broth is built from chicken and pork bones simmered at a gentle, never rolling, boil so the liquid stays clear and golden rather than turning cloudy. Seasoning comes from salt alone - no miso, no soy sauce - which places the burden of flavor entirely on the quality of the stock. Medium-wavy noodles are the standard choice, their curls catching just enough broth in each bite. Toppings are kept minimal: a slice or two of chashu pork, strips of menma bamboo shoots, and chopped scallion. The appeal of shio ramen lies in its transparency, both visual and gustatory - there is nowhere for imperfections to hide, and every sip delivers a clean, uncluttered umami.
Okinawa Soba (Thick Wheat Noodles with Braised Pork Belly)
Okinawa soba is a regional Japanese noodle dish from Okinawa featuring thick wheat noodles in bonito-based broth, topped with braised pork belly. The pork belly is blanched for three minutes to remove impurities, then slowly simmered in soy sauce, mirin, and sugar until the fibers turn soft and the meat absorbs a sweet-salty glaze. The bonito dashi broth is clear and subtly savory, seasoned lightly with soy sauce to complement rather than compete with the rich pork. Rinsing the cooked noodles briefly in warm water removes excess starch so the broth stays clean when poured over them. Bonito flakes placed on top just before serving release a smoky, oceanic fragrance, and sliced scallion adds a fresh green accent to the warm, meaty bowl.
Sapporo Miso Ramen (Hokkaido-Style Rich Miso Broth Ramen with Pork)
Sapporo miso ramen is a Hokkaido specialty featuring a thick broth designed to provide warmth during cold winters. The cooking process begins by sautéing minced garlic and ginger, followed by ground pork to render its fat. Cabbage and bean sprouts are then stir-fried briefly over high heat to maintain their crisp texture. The base uses a chicken broth mixed with miso paste. The miso is dissolved into the hot liquid after turning off the heat, as boiling would disperse its aroma. The dish is assembled by pouring this rich broth over separately cooked thick, curly ramen noodles that trap the savory soup in their curves. It is finished with sweet corn kernels and a pat of butter placed in the center. As the butter melts into the hot broth, it adds a smooth texture and rich flavor.

Roasted Kabocha Miso Nut Salad
Kabocha squash is sliced into half-moons and roasted in a hot oven until the cut surfaces caramelize and the flesh turns chestnut-soft and dry in the best possible way. The dressing combines white miso, rice vinegar, and maple syrup into a mixture where salt, acid, and a restrained sweetness reinforce each other and amplify the roasted squash underneath. Arugula provides the peppery, slightly bitter base that keeps the salad from tipping too sweet. Chickpeas add lean protein and a firm, satisfying chew that holds up against the tender squash. Walnuts, crushed roughly rather than chopped fine, contribute crunch and a deep, roasted nuttiness that layers well with the soft squash in each forkful. The contrast between textures, tender squash against resistant walnut, is what makes this salad interesting across every bite. Autumn kabocha, at the peak of its natural sugar content, delivers the most pronounced sweetness, and the dish is filling enough to stand as a vegetarian main course with nothing else alongside it. If using refrigerated squash, adjust oven time and temperature to ensure even caramelization.
Steak Rice Bowl (Seared Beef with Soy-Garlic Glaze over Rice)
A thick-cut beef steak is seared at high heat until a deep brown crust forms, then sliced and fanned over a bowl of hot rice. A glaze of soy sauce, garlic, and mirin is spooned over the slices, coating them in a glossy, caramelized finish. As the warm rice absorbs the pan juices, each spoonful carries the full weight of the beef's seared flavor. A runny fried egg or a small dab of wasabi on the side balances the richness with creaminess or heat. Controlling resting time and grain texture helps the ingredients cook evenly while keeping the final seasoning balanced.
Korean Cinnamon Persimmon Punch
Sujeonggwa is a Korean cinnamon-ginger punch made by simmering cinnamon sticks and sliced ginger in water for 25 minutes, then straining and sweetening the clear liquid with dark brown sugar. The warm, slightly sweet spice of cinnamon and the sharp rising heat of ginger meet the molasses-toned depth of the sugar, building a flavor that is spicy, sweet, and aromatic in equal measure. Quartered dried persimmon slices are added to the chilled punch, where they slowly absorb the liquid and soften into a jam-like texture over time, while floating pine nuts contribute a gentle nuttiness to each sip. Overnight refrigeration in a sealed container melds the individual flavors into something more unified, making the punch cleaner and more rounded when served cold. Sujeonggwa has long been served at Korean holiday tables during Lunar New Year and ancestral rite ceremonies, and its spiced warmth is also considered a natural digestive aid after heavy meals.

Katsu Sando (Japanese Crispy Pork Cutlet Sandwich)
Katsu sando is a Japanese sandwich built around a thick, crispy pork cutlet pressed between slices of soft milk bread. The pork loin is sliced at least two centimeters thick, pounded lightly to tenderize, seasoned with salt and pepper, then coated in flour, beaten egg, and coarse panko breadcrumbs before being lowered into oil at 180 degrees Celsius. The result is a deep golden crust that shatters on the first bite while the interior stays moist and tender. Tonkatsu sauce, a thick condiment with a fruity, sweet-savory profile similar to Worcestershire, is spread generously on one side of the bread, while a thin layer of Japanese mayonnaise goes on the other. Finely shredded cabbage is layered beneath the cutlet, providing a fresh, watery crunch that cuts through the richness of the fried meat. The crusts are trimmed from the bread, the sandwich is pressed firmly and sliced cleanly in half, and the cross-section of pale bread, pale cabbage, and dark golden cutlet becomes the defining visual of the dish. Katsu sando works as a packed lunch, a picnic item, a late-night snack, or a quick meal at the counter of a butcher shop in Tokyo.
Dipping Ramen (Japanese Thick Noodles with Concentrated Dipping Broth)
Tsukemen is a Japanese dipping ramen where thick noodles and a concentrated broth are served separately. The broth - typically tonkotsu or seafood-soy based - is reduced to roughly double the intensity of standard ramen soup. Noodles are rinsed in cold water after boiling, which firms their texture and creates a temperature contrast when dipped into the hot broth. Toppings such as chashu pork, soft-boiled egg, and nori are arranged alongside the noodles. The recipe takes about 50 minutes, with most time spent building and reducing the dipping broth.
Japanese Dan Dan Ramen (Sesame Cream Broth with Spicy Pork)
Tantanmen is the Japanese adaptation of Sichuan dan dan noodles, served as a ramen with a thick sesame-cream broth. Ground pork is stir-fried with doubanjiang and spooned over the bowl along with chili oil. The sesame base gives the soup a dense, nutty body, while the chili oil adds a slow-building heat. Standard ramen noodles are used, paired with bok choy or scallions. Preparation takes about 45 minutes, with most of the effort going into building the sesame broth and seasoning the pork topping.
