Instructions
1PREPARE THE BONES: Blanch all pork and chicken bones in boiling water for 2-3 minutes to remove impurities and excess blood, then rinse thoroughly under cold running water until the water runs clear. This critical step ensures your final broth will be clear and clean-tasting rather than cloudy or gamey. Pat the bones dry with paper towels before proceeding.
2CHAR THE AROMATICS: Cut the onion in half and char the cut sides directly over a gas flame or in a dry skillet until blackened and caramelized, about 3-4 minutes per side. Smash the ginger with the side of a knife and char it briefly as well, along with the garlic cloves. This charring process adds a subtle smoky depth and umami complexity to the broth that cannot be achieved any other way.
3SIMMER THE BROTH: Place the cleaned bones and charred aromatics into a large stockpot and cover with 3 liters of water. Bring to a rolling boil, then immediately reduce heat to maintain a gentle simmer (small bubbles should break the surface occasionally, not vigorously). Skim off any foam or impurities that rise to the top during the first 30 minutes using a fine mesh strainer or spoon. Continue simmering for 12-14 hours, adding water as needed to maintain the original level, until the broth turns a rich milky white color and becomes intensely flavored.
4PREPARE THE CHASHU PORK: While the broth simmers, tie the pork belly into a tight roll using kitchen twine, then blanch it in boiling salted water for 5 minutes to clean the surface. In a separate pot, combine soy sauce, mirin, sake, and sugar, then add the pork belly and bring to a simmer. Cook covered over low heat for 2-3 hours until the meat is extremely tender and easily pierces with a fork, turning occasionally to ensure even cooking and browning.
5SOFT-BOIL THE EGGS: Bring a pot of water to a boil and carefully add 4 room-temperature eggs, then simmer for exactly 6-7 minutes depending on your preferred yolk consistency (6 minutes for runny, 7 for slightly firmer). Immediately transfer to an ice bath to stop the cooking process, then carefully peel under cool running water once completely chilled. Once peeled, marinate the eggs in a mixture of soy sauce, mirin, and a splash of the pork braising liquid for at least 2 hours for maximum flavor.
6STRAIN AND SEASON THE BROTH: Carefully strain the finished tonkotsu broth through a fine mesh strainer into a clean pot, discarding the solids, then season to taste with salt and soy sauce. The broth should taste rich, savory, and pork-forward without being overly salty. You should have approximately 2-2.5 liters of finished broth; if you have less, you can add some water and adjust seasonings accordingly.
7COOK THE NOODLES AND ASSEMBLE: Bring a separate pot of salted water to a boil and cook the fresh ramen noodles according to package directions, usually 3-4 minutes, stirring occasionally to prevent sticking. Drain the noodles and divide among four warm bowls. Ladle the hot tonkotsu broth over the noodles, then top each bowl with a slice of chashu pork, a halved soft-boiled egg, and portions of green onions, nori, sesame seeds, and bamboo shoots. Serve immediately while the broth is still steaming hot.
