Phat Woon Sen Pu — Crab Glass Noodle Casserole / ผัดวุ้นเส้นปู
Phat woon sen (stir-fried glass noodles) with crab is a premium Thai-Chinese preparation cooked in a clay pot (mo din) — the glass noodles are soaked until just pliable, then layered in the clay pot with fresh ginger, spring onion, coriander root, white pepper, and oyster sauce, then fresh crab pieces are placed on top and the pot is sealed and steamed-stir-fried simultaneously over high heat. The clay pot retains and equalises heat, cooking the crab and noodles simultaneously and allowing the crab juices to soak into the noodles. This dish demonstrates the Thai-Chinese technique of clay-pot cooking as a flavour amplification method.

The Method
1
Soak the glass noodles in cold water until just pliable, leaving a slight resistance to the tooth, so that the noodles do not turn to mush during the final cooking inside the sealed pot. Drain them well and set aside. They will finish cooking in the clay pot; noodles that are already fully soft at this stage will be overcooked by the end.
2
Place the clay pot (mo din) over high heat and allow it to pre-heat until the interior is uniformly hot to the hand held above it, so that the moment the noodles and crab go in they begin cooking immediately rather than sitting in a slowly warming vessel. An insufficiently heated clay pot produces slow, uneven cooking and fails the technique entirely.
3
Lay the drained glass noodles into the pre-heated clay pot, then distribute the ginger slices, spring onion lengths, and bruised coriander root evenly over and through the noodles so the aromatics perfume every layer rather than sitting in one concentrated pocket. Spoon the oyster sauce over the noodles and scatter the white pepper across the surface.

4
Arrange the fresh crab pieces in a single layer on top of the noodle and aromatics base, so that the crab's steam and juices descend as it cooks and saturate the noodles below rather than being absorbed by them before they can move. This is where the dish lives or dies: crab buried beneath the noodles cannot steam freely and cannot surrender its juices downward into them.
5
Cover the clay pot with its lid and cook over high heat for 8–10 minutes without lifting the lid, so the sealed interior holds and concentrates the crab steam — each intrusion releases it and disrupts the infusion of crab juices into the noodles. The dish is ready when a deep, intensified shellfish aroma escapes from the edges of the lid.
6
Remove the pot from the burner when the noodles are just cooked through and the crab shells are fully red but the flesh reads approximately 80% done, trusting that the retained heat of the clay pot will carry both noodles and crab to the finish after the flame is gone. Bring the sealed pot directly to the table and lift the lid at service.

Quality Hierarchy
01
Reserve — Live mud crab or live blue crab, dispatched immediately before preparation; crab juices fully intact and at maximum sweetness.
02
Estate — Whole fresh crab purchased live from a specialist wet market, killed and broken down to order; glass noodles from a Thai-Chinese producer using pure mung bean starch.
03
Market — Fresh whole crab from a reliable fishmonger, not previously frozen; standard supermarket glass noodles.
04
House — Frozen crab portions, thawed; yields a serviceable result but the infusion of crab liquid into the noodles is markedly reduced.

Sensory Tests
◇Touch. Soaked glass noodles bend without snapping but resist firm pressure between the fingers — still slightly underdone.
◇Touch. Clay pot interior radiates immediate, even heat to the palm held 10 cm above — fully pre-heated.
◇Smell. A concentrated, sweet shellfish steam escapes from the rim of the sealed lid after 8–10 minutes — the crab is cooked and its juices have descended into the noodles.
◇Sight. All crab shells have turned fully red and the glass noodles have become translucent and glistening with absorbed crab liquid.
◇Where it lives or dies. The crab pieces must be placed on top of, not beneath, the noodles — if buried, they cannot steam downward and the noodles will never become crab-saturated.
