About this dish
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.

Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Control
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.
Cook 200 g ramen noodles until firm, then serve immediately with hot broth, chashu, egg, and green onion.

- Avoid this
- As the broth reduces, add hot water as needed and do not lower the heat to a gentle simmer.
- Storage and reheating
- Making chashu a day ahead and refrigerating makes it easier to slice thinly.
