Rich Tonkotsu Ramen

About This Recipe

Tonkotsu ramen originated in Fukuoka, Kyushu, and is defined by its rich, opaque pork bone broth achieved by boiling bones at a rapid boil for hours. The result is an intensely savoury, collagen-rich soup unlike any other. This recipe streamlines the process without sacrificing depth.

Ingredients

Serves 4

• 1 kgpork trotters and neck bones(blanched)
• 500 gpork belly(for chashu)
• 400 gfresh ramen noodles
• 4soft-boiled eggs(marinated in soy/mirin)
• 100 mlsoy sauce
• 60 mlmirin
• 2 tbspsake
• 1 tbspwhite miso
• 6 clovesgarlic
• 5 cmfresh ginger(sliced)
• 4 sheetsnori (dried seaweed)
• 100 gmenma (bamboo shoots)
• 4 stalksgreen onions(thinly sliced)
• 2 tbspsesame oil
• 2 tbsptoasted sesame seeds

Instructions

1. 1

   Blanch the bones

   Cover bones with cold water. Bring to a boil for 10 minutes. Drain and rinse bones and pot thoroughly. This removes blood and impurities that would make the broth grey.

2. 2

   Build the broth

   Return cleaned bones to the pot. Cover with 3 litres cold water. Add garlic and ginger. Bring to a vigorous boil (not a simmer — tonkotsu requires a hard boil to emulsify the fat and collagen into a white, creamy broth). Boil hard for 3–4 hours, adding water as needed.

   The key to tonkotsu's opacity is the violent boil. A gentle simmer will produce a clear stock — completely different character.

3. 3

   Make chashu pork

   Roll pork belly tightly, tie with kitchen string. Sear all over in a hot pan until browned. In a small pot, combine soy, mirin, sake, 200ml water, 1 tbsp sugar. Add pork belly. Simmer covered 90 minutes until tender. Rest in braising liquid.

4. 4

   Marinate eggs

   Boil eggs 7 minutes for jammy yolk. Peel and marinate in a mix of 3 tbsp soy + 2 tbsp mirin + 100ml water for at least 2 hours.

5. 5

   Season the broth (tare)

   Strain broth. Season with miso, remaining soy sauce, and sesame oil. Taste — it should be intensely savoury. Adjust salt if needed.

6. 6

   Cook noodles and assemble

   Cook noodles per package. Divide into bowls. Ladle hot broth over noodles. Top with sliced chashu, halved marinated egg, bamboo shoots, green onion, nori and sesame seeds.

Variations

• •

  Spicy tonkotsu: stir 1–2 tbsp chilli bean paste (doubanjiang) into the tare.

• •

  Vegan tantanmen: replace broth with sesame/soy based broth, use tofu and ground sesame instead.

Storage

Broth keeps refrigerated 5 days or frozen 3 months. Store components separately.
