Yakiton and Japanese Pork Skewer Culture Beyond Yakitori

Ingredients

• Pork cuts — select two or three for a mixed plate
• 250 g kashira (pork temple/head meat), cut into 3–4 cm pieces; the most marbled cut, collagen-rich
• 250 g butabara (pork belly), cut into 3–4 cm pieces, skin on or off
• 200 g nankotsu (cartilage), scored before skewering to facilitate heat penetration
• 150 g hatsu (pork heart), trimmed and cut into 3–4 cm pieces
• 150 g rebaa (pork liver), trimmed; requires careful temperature management — 70 °C core minimum
• For the tare glaze
• 120 ml soy sauce
• 60 ml mirin
• 30 ml sake
• 15 g sugar
• For shio seasoning
• 2 tsp fine sea salt, applied directly to skewers before grilling
• 1 lemon, cut into wedges, served alongside shio-seasoned skewers
• Equipment
• 16–20 bamboo or metal skewers, bamboo skewers soaked in water if grilling over binchotan or open flame

Method

1. 1
   Prepare the tare. Combine soy sauce, mirin, sake, and sugar in a small saucepan over medium heat. Stir until the sugar dissolves, then reduce until the glaze coats the back of a spoon and holds a trail drawn through it. Remove from heat and reserve. The tare is ready when it is glossy and has the consistency of a light syrup.
2. 2
   Score nankotsu pieces with two shallow cuts before skewering. Thread all cuts firmly and tightly onto skewers — three to four pieces per skewer depending on cut size. Loose skewering causes rotation on the grill and uneven cooking, particularly for nankotsu. Each skewer should feel rigid when held horizontally. Assign cuts to shio or tare: shio for leaner cuts (butakushi, hatsu, rebaa); tare for richer, fattier cuts (butabara, kashira).
3. 3
   Prepare the grill. Bring binchotan charcoal to full ignition — it should glow red-orange with a white-grey ash coating and emit intense, even radiant heat. Establish a two-zone fire: one side at high heat for searing and cartilage work, one side at moderate heat for collagen-rich cuts requiring longer, slower rendering. A cast iron ridged grill pan over maximum heat, preheated for five minutes, is the appropriate home substitute.
4. 4
   This is where the dish lives or dies. Grill kashira over medium binchotan heat, four to five minutes per side. Do not rush. The fat must render slowly, building a Maillard crust incrementally while the collagen softens. Monitor constantly for flare-ups from dripping pork fat — move skewers to the cooler zone immediately if flames rise. The skewer is done when the exterior carries a deep, mahogany crust and the fat between the muscle fibres has rendered to a glistening, gelatinous sheen; the meat yields to gentle pressure without resistance.
5. 5
   Grill nankotsu over the high-heat zone. The scored cartilage pieces require intense surface heat to char the exterior while the interior reaches a yielding but structured crunch. Turn once. The skewer is ready when the exterior is visibly charred at the edges and the cartilage offers resistance to a bite without being brittle — the interior crunch must remain.
6. 6
   Grill rebaa (liver) with careful attention to internal temperature. Cook over medium-high heat, turning regularly. The minimum safe core temperature is 70 °C — check with an instant-read thermometer. The exterior should be firm and lightly coloured; the interior must not be raw. Do not overcook: liver becomes granular and unpleasant once the core exceeds 75 °C.
7. 7
   Apply tare to designated skewers during the final minute of grilling — brush once, allow thirty seconds for the glaze to set and caramelise, then brush once more. Do not over-apply tare to fatty cuts such as butabara; a single light coat is sufficient. Shio skewers receive only a uniform pinch of fine sea salt before grilling; serve immediately with lemon wedges. All skewers should arrive at the table directly from the grill — the yakiton format demands continuous, immediate service.
