Chengdu Dandan Mian with Sesame School (成都担担面芝麻派)

Ingredients

• For the sesame sauce
• 120 g Chinese sesame paste (zhima jiang), roasted style; not Middle Eastern tahini
• 3 tbsp light soy sauce, used to thin the paste, not water
• 1 tsp sugar
• 2 tbsp Sichuan pepper oil (hua jiao you), or to taste
• 2 tbsp chilli oil, with sediment
• 1 tbsp rice vinegar
• For the pork topping
• 200 g minced pork, not too lean
• 2 tbsp doubanjiang (Pixian broad bean paste), finely chopped if coarse
• 1 tbsp light soy sauce
• 1 tsp Shaoxing rice wine
• 1 tbsp neutral oil
• For the bowl
• 400 g fresh thin wheat noodles, or 320 g dried; alkaline-style preferred
• 60 g Yibin ya cai (芽菜, preserved mustard), rinsed lightly if very salty
• 4 spring onions, finely sliced, green parts only

Method

1. 1
   Fry the minced pork in neutral oil over high heat, breaking it apart, until it has rendered its fat and turned evenly brown and dry. Add the doubanjiang and stir-fry for one further minute until the oil runs red and the paste smells fragrant. Add the soy sauce and Shaoxing wine, toss briefly, then remove from the heat. The pork is ready when it is separated into fine, dry grains rather than clumps, and the oil is visibly brick-red.
2. 2
   In a bowl, combine the Chinese sesame paste with the light soy sauce. Stir steadily — the paste will seize before it loosens; continue until the mixture is smooth and uniform. Add the sugar, chilli oil, Sichuan pepper oil, and rice vinegar. Stir to a cohesive sauce. This is where the dish lives or dies: the paste must be thinned with soy sauce alone at this stage, achieving a consistency that coats a spoon in a thick, even film without pooling. If Middle Eastern tahini has been substituted, the result will be lighter in colour and noticeably less roasted in aroma — a serviceable but distinct outcome.
3. 3
   Bring a generous pot of unsalted water to a full rolling boil. Reserve one ladle (approximately 80 ml) of the boiling water before adding the noodles. Cook the noodles until just tender with no raw core remaining, then drain without rinsing.
4. 4
   Add the reserved noodle cooking water to the sesame sauce in small increments, stirring after each addition, until the sauce thins to a consistency that will coat the noodles evenly without pooling at the base of the bowl. The correct texture coats a lifted noodle strand in a translucent, clinging film rather than a heavy mass.
5. 5
   Allow the drained noodles to rest briefly until they reach room temperature — they will absorb sauce more evenly at this temperature than if dressed while steaming hot. Divide the noodles among four bowls. Spoon the sesame sauce over each portion. Top with the fried pork, ya cai, and spring onion. Serve immediately; the bowl is ready when each element remains visually distinct on the surface before the diner mixes them.
