Sichuan Strange-Flavour Cold Chicken (Guai Wei Ji)

Ingredients

• For the chicken
• 1 (about 1.4 kg) whole chicken, free-range preferred
• 1 cucumber, shredded
• 2 spring onions, finely sliced
• 1 tbsp sesame seeds, toasted
• For the guai wei sauce
• 3 tbsp sesame paste (zhima jiang), Chinese-style, not tahini
• 2 tbsp light soy sauce
• 2 tbsp chilli oil (la you), with sediment
• 1 tbsp Sichuan peppercorn oil (hua jiao you)
• 1 tbsp Chinkiang black rice vinegar
• 1 tbsp sugar
• 1 tsp sesame oil
• 2 cloves garlic, minced to a paste
• ¼ tsp ground white pepper, the bitter element — subtle

Method

1. 1
   Place the whole chicken in a pot and cover with cold water. Bring to a full boil, then reduce to a bare simmer. Poach — using the bai qie ji method — until just cooked through: the leg joint should run clear when pierced. Remove the chicken immediately and submerge it in iced water. Hold it there until the flesh is cold to the core and the skin has tightened and turned slightly gelatinous to the touch.
2. 2
   While the chicken chills, build the guai wei sauce. Place the sesame paste in a bowl and loosen it gradually with the soy sauce, stirring in one direction until the mixture is uniform and fluid — no lumps, no separation. Add the chilli oil with its sediment, the Sichuan peppercorn oil, vinegar, sugar, sesame oil, garlic paste, and white pepper. Blend until the sauce is smooth, cohesive, and flows from a spoon in a steady, even ribbon rather than dropping in heavy clots. This is the step on which the dish lives or dies: taste now, adjusting each element in turn — ma, la, tian, suan, xian, xiang, ku — until no single sensation dominates and the palate shifts through all seven in sequence.
3. 3
   Drain and dry the chilled chicken. Chop through the bone into neat pieces in the Chinese manner, or strip the meat cleanly by hand into bite-sized shreds. The flesh must be cold throughout — not cool, not room temperature. Arrange the shredded cucumber across a serving plate as the base.
4. 4
   Lay the chicken pieces over the cucumber. Spoon the guai wei sauce evenly over the top — it should coat each piece and flow slightly at the edges, not pool thickly beneath. Scatter toasted sesame seeds and sliced spring onion over the dish. The surface should look glossy, the garnish should stand above the sauce, and the whole plate should carry a sharp, roasted, chile-laden aroma before it reaches the table.
