πŸ“ About This Recipe

Born in 1974 at the legendary Yoshimuraya in Yokohama, Iekei Ramen is a cult-favorite style defined by its 'House' (Ie) lineage and punchy, soul-warming profile. This dish features a thick, emulsified pork and chicken bone broth blended with a potent shoyu tare and a signature layer of golden chicken oil (chiyu). It is famously characterized by its short, thick, chewy noodles and the essential trio of toppings: smoky chashu, blanched spinach, and large sheets of crisp nori.

πŸ₯— Ingredients

The Broth (Soup Base)

  • 2 kg Pork neck bones or femur bones (soaked in cold water for 2 hours to remove impurities)
  • 2 pieces Chicken carcasses (cleaned of organs)
  • 4 liters Water (filtered is best)
  • 1 head Garlic (halved crosswise)
  • 50 g Ginger (sliced)

The Shoyu Tare (Seasoning)

  • 200 ml Koikuchi (Dark) Soy Sauce (high quality)
  • 50 ml Mirin
  • 1 piece Kombu (5x5cm square)
  • 1 teaspoon Salt

The Chiyu (Chicken Oil)

  • 300 g Chicken skin and fat (finely chopped)
  • 2 pieces Green onion tops

Noodles and Toppings

  • 4 portions Thick, flat Ramen Noodles (look for 'Iekei style' or thick wavy noodles)
  • 8 slices Smoked or Braised Pork Chashu (thickly cut)
  • 1 bunch Fresh Spinach (blanched and squeezed dry)
  • 12 sheets Nori (Seaweed) (large squares)
  • 2 pieces Green onions (finely sliced)

πŸ‘¨β€πŸ³ Instructions

  1. 1

    Prepare the bones: Place pork and chicken bones in a large pot, cover with water, and bring to a boil. Boil for 10 minutes, then drain and scrub the bones under cold water to remove all grey scum and blood.

  2. 2

    Start the broth: Return the cleaned bones to a clean pot with 4 liters of water. Bring to a vigorous boil. Use a skimmer to remove any rising foam.

  3. 3

    Simmer: Add the garlic and ginger. Maintain a rolling boil (not a simmer) for 6-8 hours. This high heat is essential to emulsify the fats into the water, creating a creamy, opaque 'Paitan' broth. Top up with water as needed to keep bones covered.

  4. 4

    Make the Chiyu: While the broth boils, place chicken fat and skin in a small saucepan over low heat. Render until the fat turns liquid and the skin becomes crispy. Add green onion tops for the last 5 minutes for aroma. Strain and set aside.

  5. 5

    Make the Shoyu Tare: Combine soy sauce, mirin, kombu, and salt in a small pot. Bring to a simmer for 5 minutes (do not boil hard). Remove kombu and set aside.

  6. 6

    Prep the Spinach: Blanch the spinach in boiling water for 30 seconds, immediately shock in ice water, squeeze out all moisture, and cut into 2-inch segments.

  7. 7

    Final Broth Polish: After 8 hours, the broth should be thick and creamy. Strain through a fine-mesh sieve into a clean pot. Discard the solids.

  8. 8

    Boil Noodles: Cook your thick noodles in a large pot of boiling water according to package instructions (usually 3-5 minutes). Iekei noodles are traditionally served slightly firm ('katame').

  9. 9

    Warm the Bowls: Pour hot water into your serving bowls to warm them, then discard the water right before assembling.

  10. 10

    Assemble: Add 3 tablespoons of Shoyu Tare and 1-2 tablespoons of Chiyu to each bowl.

  11. 11

    Combine: Pour 350ml of the piping hot broth into the bowl and stir gently to combine with the tare and oil.

  12. 12

    Add Noodles: Carefully place the cooked noodles into the broth, lifting them with chopsticks to ensure they are coated and folded neatly.

  13. 13

    Garnish: Top each bowl with 2 slices of chashu, a mound of blanched spinach, and a sprinkle of green onions. Finish by tucking 3 large nori sheets into the side of the bowl so they stand upright.

  14. 14

    Serve: Serve immediately while the nori is still crisp and the broth is steaming.

πŸ’‘ Chef's Tips

Don't skimp on the boiling time; a rolling boil is what creates the creamy texture, whereas a simmer results in a clear soup. If the broth is too thick or salty, you can dilute it with a little hot water or unsalted chicken stock. Authentic Iekei uses 'Sakai Seimen' style noodlesβ€”if you can't find them, use the thickest fresh ramen noodles available. For an extra punch, serve with a side of grated garlic and doubanjiang (chili paste) so diners can customize their spice level. Always use high-quality Nori, as it is meant to be dipped into the fatty broth and eaten with rice.

🍽️ Serving Suggestions

Serve with a side of plain white rice; dipping the broth-soaked nori into the rice is the traditional way to eat Iekei. Pair with a cold, crisp Japanese lager to cut through the richness of the pork fat. A side of pan-fried Gyoza provides a lovely textural contrast to the chewy noodles. Offer a small dish of pickled ginger (beni shoga) to cleanse the palate between bites.
