Japanese Tori Paitan: White Chicken Bone Broth Ramen and Collagen Extraction Technique

Ingredients

• 1 kg chicken backs, rinsed
• 500 g chicken feet (tori kara), rinsed
• 500 g chicken wings (teba), rinsed
• 30 g fresh ginger, sliced, added in final 30 minutes
• For the tare
• 60 ml light soy sauce
• 20 ml mirin
• To serve
• 400 g fresh ramen noodles, or 320 g dried, cooked separately

Method

1. 1
   Place chicken backs, feet, and wings in a large stockpot. Cover with cold water. Bring to a full rolling boil over high heat. Once boiling, drain and rinse every piece under cold running water, discarding the blanching liquid. This removes blood, impurities, and off-flavours before the main extraction begins. The pieces should be clean with no grey scum.
2. 2
   Return the cleaned bones to the pot. Cover with cold water by at least 5 cm. Bring to a full, aggressive rolling boil over high heat — not a simmer, not a gentle bubble, but a hard boil that churns the surface. Maintain this vigour for the entirety of the cook: 3 hours on the stovetop, adding fresh water as needed to keep the bones submerged. The broth will turn white and opaque within the first 30 minutes. Do not skim the fat: the emulsified chicken fat is the defining character of tori paitan. The dish lives or dies at this stage — a gentle simmer produces clear stock; only a sustained rolling boil physically emulsifies the fat and extracts collagen to create paitan.
3. 3
   In the final 30 minutes of cooking, add the sliced ginger directly to the pot. It cuts the heavier chicken fat notes and adds aromatic brightness without obscuring the clean poultry depth. The broth at this point should be viscous, white, and coat a spoon like a light sauce.
4. 4
   Strain the broth through a fine-mesh sieve, pressing the solids lightly. Discard bones and ginger. The finished broth should be opaque white, viscous, and unctuous — it will set to a loose jelly when cooled, confirming adequate gelatin extraction.
5. 5
   Calibrate the tare: combine light soy sauce and mirin in a small pan and warm gently to dissolve. Because tori paitan carries inherent salt and fat in the broth itself, the tare should be lighter than that used for tonkotsu. Add tare to each serving bowl before ladling the hot broth — begin conservatively and taste before adjusting. The broth should taste balanced and clean, with deep sweet poultry flavour; over-taring creates an unbalanced bowl.
6. 6
   Cook noodles separately in boiling unsalted water according to their type. Drain. Place noodles in the seasoned bowl. Ladle approximately 300 ml of hot paitan broth over. The broth should coat the noodles visibly, remaining opaque and creamy to the eye, with a silky feel as the suspended fat coats the palate.
