Yum Woon Sen (ยำวุ้นเส้น)

Chewy glass noodles tossed in lime, fish sauce and sugar, with crisp dried shrimp, fried peanuts and a fresh tomato crunch. The salad that eats like a full lunch.

Yum woon sen (ยำวุ้นเส้น) — glass noodle salad with minced pork, dried shrimp and roasted peanuts on a banana leaf

The Old-Style Version, Dry Not Sloppy

ยำวุ้นเส้น is the glass-noodle member of the Thai yum family — the same lime-fish-sauce logic as som tum, transferred to slippery, translucent วุ้นเส้น, mung-bean vermicelli. The TrueID source labels its version โบราณ — ancient, and promises it two ways: เส้นเหนียวนุ่ม ไม่อืด — noodles chewy-soft, not soggy — and แบบแห้ง ๆ ไม่เฉอะแฉะ, a dry salad, not a puddle. The noodles carry the dressing; they don't swim in it.

The crunch comes in threes: ถั่วลิสงทอด, peanuts fried from cold oil so they cook through to the centre without burning; กุ้งแห้ง, dried shrimp crisped in the same oil until they smell like the sea; and raw shallot, chilli and tomato cut fresh at the end. The pork is the quiet protein — blanched together with the noodles so nothing gets washed in a second pot.

And the dressing is the whole point: six tablespoons of lime to six of fish sauce, two of sugar — sharp, salty, just sweetened. The source is proud of what it doesn't contain: no MSG, the flavour built on the dried shrimp and the fry oil instead.

The Recipe (serves 2–3 — the TrueID โบราณ version, no MSG)

The Method

  1. Soak the noodles while you prep the vegetables and herbs.
  2. Fry the peanuts from cold oil over a medium-low heat, stirring constantly until golden — then lift out and drain.
  3. Crisp the dried shrimp in the same oil until fragrant and crunchy. Drain.
  4. Blanch noodles and pork together. Noodles into boiling water; just before done, add the minced pork and cook through. Drain both as one.
  5. Dress and toss. Lime juice, fish sauce and sugar stirred until the sugar dissolves; everything into the bowl with the dressing, tossed once; spring onions and coriander over the top. Serve.

Where Thai Sources Disagree

Dried shrimp and peanuts. The โบราณ version builds its depth on them; the Kapook minced-pork version uses neither — it leans on its dressing. Two generations of the same salad.

Pickled garlic brine. Kapook's dressing is fish sauce, lime and น้ำกระเทียมดอง — the brine from the pickled-garlic jar — plus the pickled garlic itself, sliced in. The โบราณ version wants none of it. The brine is the shop-stall's sour-salty shortcut.

The noodle trick. Kapook blanches the noodles, then shocks them with room-temperature water — the น็อก (knock) that sets them chewy so they never go soggy. The โบราณ version simply times the blanch. Same goal, different route.

Celery. Kapook adds ขึ้นฉ่าย (Chinese celery) and onion; the โบราณ version keeps shallot and skips the celery. Both claim the dish; the crunch differs.

The loaded version. One Wongnai cook (134K reads) makes a fifteen-minute modern build — cabbage, shimeji mushrooms, hot dogs, หมูยอ pork sausage, carrot — blanched together and dressed. Delicious, but it's a different dish wearing the same name.
