Parboil the 6 pork legs and 6 pork knuckles in a large pot for 10 minutes. This helps to remove impurities.

Rinse the parboiled bones thoroughly under cold water until clean.

Clean the large pot thoroughly to remove any residue from parboiling.

Fill the cleaned pot with fresh water. The amount will vary depending on your pot size, but aim for approximately 7 to 8 liters, ensuring the bones will be fully submerged.
Add the cleaned pork legs and pork knuckles back into the pot with the fresh water.

Bring the water to a boil, then reduce heat to a simmer. Cook for 8-10 hours, continuously checking the water level and skimming any impurities that float to the top. Replenish water as needed to keep bones submerged.

Once the broth achieves a beautiful thick white consistency, add the aromatics: 6 green onions, 1 white onion, 1 cup of sliced ginger, and 1 half Fuji apple. Optionally, add a little more water if needed.

Continue to boil the broth with the aromatics for another 2 hours.

Strain the finished broth through a fine-mesh sieve or cheesecloth to remove all solids. Set aside.

For the Tare: In a small saucepan, combine 1/4 cup mirin and 1/4 cup sake. Cook over medium heat until the alcohol has cooked out, about 3-5 minutes.

Add 1 1/2 tablespoons red miso, 1 1/2 tablespoons black sesame miso (or any available miso), 1 tablespoon hondashi, and 1 tablespoon sesame seeds to the saucepan. Cook for another 3-5 minutes, stirring constantly.

Transfer the tare mixture to a blender and blend until smooth. Set aside.

For the Chashu: Tightly wrap the 2 lb pork belly and tie it securely with kitchen twine.

Sear the pork belly on all sides in a large pot or Dutch oven until browned.

Add the braising liquid to the pot: 1 cup dark soy, 2/3 cup mirin, 1/2 cup soy sauce, and enough water to almost submerge the pork belly.

Bring the liquid to a simmer, then cover the pot and cook for 2-3 hours, flipping the pork belly halfway through. The pork should be very tender.

Let the pork belly cool completely in the braising liquid. This allows it to absorb more flavor and remain moist.

Transfer the cooled pork belly and its braising liquid to a ziplock bag and refrigerate overnight (at least 8 hours).

The next day, remove the chashu from the braising liquid. Slice the chashu into disks. Optionally, torch the sliced chashu for a caramelized finish.

For the Marinated Eggs: Boil 3 large eggs for exactly 6 minutes and 20 seconds. This results in a jammy yolk.

Immediately transfer the boiled eggs into an ice bath to stop the cooking process.

Carefully peel the eggs. Combine them with the reserved chashu braising liquid in a container. Let the eggs marinate for about 12 hours in the refrigerator.

For the Optional Aroma Oil: Slice ginger, garlic, and scallions. Heat oil to 350°F (175°C).

Carefully pour the hot oil over the sliced aromatics in a heat-proof bowl. Let the oil cool completely. Strain out the aromatics if desired.

For the Optional Bamboo Shoots: If using, soak bamboo shoots in some of the chashu braising liquid for about an hour to infuse flavor.

To Assemble the Ramen: Cook your ramen noodles according to package directions. Place cooked noodles into serving bowls.

Heat the Tonkotsu broth and the tare. Add a desired amount of tare to each bowl (start with 1-2 tablespoons and adjust to taste). Pour the hot Tonkotsu broth over the noodles and tare, stirring gently to combine.

Arrange slices of chashu on top of the noodles. Cut a marinated egg in half and add to the bowl.

Garnish with sliced green onions, narutomaki, nori, and the optional marinated bamboo shoots. Drizzle with the optional aroma oil if desired. Serve immediately.
