Wuhan Hot and Dry Noodles (Re Gan Mian) — Sesame Paste Mastery

Ingredients

• 200 g Alkaline noodles (jian mian), fresh or dried; characteristic yellow colour and springy texture
• 1 tbsp Sesame oil, for tossing pre-cooked noodles
• For the dressing
• 3 tbsp Chinese sesame paste (zhima jiang), pure Chinese variety — thick, nutty, darker than tahini; not tahini
• 2 tbsp Hot water or cold sesame oil, to thin paste to pouring consistency
• 1 tbsp Light soy sauce
• 1 tsp Rice vinegar
• 1 tbsp Chili oil, optional; authentic Wuhan re gan mian is not spicy
• To finish
• 30 g Su cai (preserved mustard tuber / pickled radish), rinsed and finely chopped; provides salty, crunchy counterpoint
• 2 Scallions, finely sliced
• 1 tsp Sesame seeds, toasted

Method

1. 1
   Cook the alkaline noodles in a large pot of boiling water to 80 per cent doneness — they should be springy but with a firm, raw centre — because they will finish cooking in the reheat later and must not turn soft at that stage. Drain immediately and toss at once with the sesame oil so that every strand is lightly coated, sealing the surface and preventing the noodles from sticking together as they cool. Spread in a single layer on a tray and leave until completely dry to the touch, not tacky; a dry surface is what lets the sesame paste grip the noodle rather than slide off it.
2. 2
   Place the Chinese sesame paste in a bowl and add the hot water or cold sesame oil a little at a time, stirring constantly, so the paste loosens gradually rather than splitting into an oily puddle with a dry lump at the centre. Work it until the consistency is smooth and pourable — it should fall from the spoon in a slow, steady ribbon, neither stiff nor watery. This is where the dish lives or dies: a paste too thick will clump and never coat the noodles evenly; too thin and the nutty depth is lost.
3. 3
   Bring a fresh pot of water to a full boil and lower the pre-cooked, dried noodles in for no more than 30 to 40 seconds, just long enough to bring them through to the centre, so they arrive in the bowl piping hot — the sauce melts into a hot noodle in a way it simply will not into a lukewarm one. They are done when they are fully springy with the characteristic chew of an alkaline noodle. Drain thoroughly; the noodles must be hot but carry no surface water, or the sauce will be diluted before it even reaches the noodle.
4. 4
   Transfer the drained noodles immediately to a bowl and spoon over the thinned sesame paste, then add the light soy sauce, rice vinegar, and chili oil, tossing vigorously so the paste coats every strand while the noodles are still hot enough to absorb it. The sauce should cling, not pool; the noodles should not be soupy. Taste: sesame dominates, soy is a background note, vinegar is a brightness rather than an acid.
5. 5
   Scatter the chopped su cai, sliced scallion, and sesame seeds over the dressed noodles. Serve at once — the noodles absorb the sauce quickly and must reach the table immediately after dressing.
