The Mise en Place
5 of 18Your prep station before cooking begins
Tare (Seasoning) (0/3)
Broth (0/4)
Broth is not milky white.
Ensure a high bone-to-water ratio and a vigorous simmer. Increase simmering time.
Broth tastes bland.
Adjust the amount of tare (soy sauce mixture) to taste. Ensure high-quality ingredients.
Chef's Notes
For richer broth, simmer pork bones for at least 8 hours, or overnight, skimming impurities regularly.
Sear pork belly slices until deeply browned and slightly crispy before adding to the broth for maximum flavor.
Garnish generously with chopped scallions, a jammy soft-boiled egg, and a drizzle of chili oil.
Broth can be made up to 3 days ahead and refrigerated. Reheat gently before serving.
The Method
PREPARE
Prep aheadRinse the pork bones (8 lb) thoroughly under cold water (5 qt) to remove any impurities.
Cloudy broth: Failure to remove blood and bone marrow residue will result in a gray, bitter broth.
Pork bones are rinsed clean.
BLANCH
Prep aheadPlace the pork bones (8 lb) in a large pot, cover with cold water (5 qt), and bring to a boil. Boil for 10 minutes to remove impurities. Drain and rinse the bones again.
Incomplete cleaning: Failing to rinse away all scum will result in a muddy, bitter broth rather than a clean, milky one.
Pork bones have been boiled and rinsed.
TRANSFER
Prep aheadTransfer the blanched pork bones (8 lb) to a clean, large stockpot. Add 5 quarts of fresh, cold water (5 qt).
Incomplete extraction: Using warm water initially can seal the pores of the bone, preventing the release of collagen.
Blanched pork bones are in the stockpot with fresh water.
ADD
Prep aheadAdd sliced ginger (2 inches) and crushed garlic (6 cloves) to the pot.
Overpowering aromatics: Do not exceed the specified amount, as ginger can dominate the delicate pork flavor.
Ginger and garlic have been added to the pot.
BRING
Time-sensitivePrep aheadBring the pot to a rolling boil, then reduce the heat to a vigorous simmer. Simmer uncovered for at least 18 hours, or up to 24 hours.
Evaporation loss: If the water level drops too low, the broth will become overly salty and dark instead of creamy.
Broth is simmering vigorously.
SKIM
Prep aheadSkim off any scum or impurities that rise to the surface during the first few hours of simmering.
Cloudy broth: Failing to remove all scum will result in a muddy, bitter-tasting final broth.
Scum and impurities have been skimmed from the broth.
STRAIN
Prep aheadAfter simmering, strain the broth through a fine-mesh sieve lined with cheesecloth. Discard the solids.
Sediment leakage: Ensure the cheesecloth is layered to catch fine bone fragments.
Broth has been strained and solids discarded.
COOL
Prep aheadCool the broth quickly in an ice bath. This helps to preserve the flavor and prevent spoilage. Once cooled, refrigerate until ready to use.
Bacterial growth: The broth must drop below 40°F quickly to prevent spoilage.
Broth has been cooled and refrigerated.
COMBINE
Prep aheadIn a small saucepan, combine soy sauce (½ cups)soy sauce (½ cups)soy sauce (¼ cups), mirin (¼ cups)mirin (¼ cups)mirin (¼ cups), and sake (¼ cups)sake (¼ cups) for the tare. Bring to a simmer over medium heat and cook for 2-3 minutes. Remove from heat and set aside.
Excessive saltiness: If the tare reduces too far, it will overpower the delicate broth.
Tare mixture has been simmered and set aside.
PREPARE
Prep aheadPrepare the chashu pork belly (1000 g). Place the pork belly in a pot and cover with water (5 qt). Bring to a boil, then reduce heat and simmer for 1 hour, or until tender.
Tough meat: Boiling too vigorously will cause the muscle fibers to tighten.
Pork belly has been simmered until tender.
COMBINE
Prep aheadIn a separate saucepan, combine soy sauce (½ cups)soy sauce (½ cups)soy sauce (¼ cups), mirin (¼ cups)mirin (¼ cups)mirin (¼ cups), sake (¼ cups)sake (¼ cups), and sugar (2 tbsp) for the chashu marinade. Bring to a simmer.
Burnt sugar: Caramelized sugar creates a bitter note that ruins the marinade balance.
Chashu marinade has been prepared and is simmering.
TRANSFER
Prep aheadTransfer the cooked pork belly (1000 g) to the marinade. Let it cool and marinate in the refrigerator for at least 4 hours, or preferably overnight.
Uneven marination: Exposed meat will dry out and remain pale, leading to uneven presentation in the final bowl.
Pork belly is marinating in the refrigerator.
SLICE
Prep aheadSlice the marinated pork belly (1000 g) into thin slices.
Tearing the meat: If the pork is too warm, it will crumble. Slice while chilled for clean, even edges.
Marinated pork belly is sliced.
PREPARE
Prep aheadPrepare the ajitsuke tamago (marinated eggs (6 large)). Gently boil eggs for 6 minutes for a runny yolk. Immediately transfer to an ice bath to stop cooking.
Overcooked yolk: Exceeding 6 minutes will result in a chalky yolk rather than a jammy one.
Eggs have been boiled and are in an ice bath.
PEEL
Prep aheadPeel the eggs (6 large) carefully and marinate in a mixture of soy sauce (½ cups)soy sauce (½ cups)soy sauce (¼ cups) and mirin (¼ cups)mirin (¼ cups)mirin (¼ cups) for at least 2 hours, or overnight.
Tearing whites: Peeling too aggressively will gouge the delicate surface of the soft-boiled egg.
Eggs have been peeled and are marinating.
HALVE
Prep aheadHalve the marinated eggs (6 large) lengthwise.
Yolk smear: A dull knife will drag the yolk, ruining the presentation of the cross-section.
Marinated eggs have been halved.
COOK
Time-sensitiveCook the ramen noodles (8 servings) according to package directions.
Overcooking: Ramen noodles lose their signature chewiness rapidly. Strain them 30 seconds before they seem fully done.
Ramen noodles are cooked.
ASSEMBLE
To assemble the ramen, add the tare to each bowl. Then, add the hot tonkotsu broth. Add the cooked noodles, followed by slices of chashu pork belly (1000 g) and half of a marinated egg. Garnish with sliced green onions (4 stalks) and sesame seeds (2 tbsp).
Temperature drop: Cold bowls will instantly drop the soup temperature, ruining the mouthfeel.
Ramen bowls are assembled with all components.
SERVE
Serve immediately and enjoy!
Soggy noodles: Noodles continue to cook in the hot broth; serve immediately to maintain the intended texture.
Ramen is served.
