Phat Pak Boong Fai Daeng — Morning Glory in Fire / ผัดผักบุ้งไฟแดง
Morning glory stir-fry with fire (fai daeng = red fire) refers specifically to the technique of stir-frying water spinach (pak boong, Ipomoea aquatica) in the highest possible wok heat, with yellow bean sauce (tao jiew), oyster sauce, garlic, and bird's eye chilli until the leaves are wilted but the stems retain crunch. The 'red fire' of the technique is the result of the oil catching the wok flame when the vegetables and sauce are tossed — the brief spectacular flare develops the characteristic smoky, slightly charred note that defines this dish. This wok-flame moment is what street cooks perform theatrically at Thai street restaurants.

The Method
1
Set the wok over the highest available flame and pre-heat it, empty, for 4–5 minutes until the first faint wisps of smoke drift across its surface, so the metal reaches a temperature that will sear rather than stew everything that touches it. Do not add oil yet.
2
Add the lard or peanut oil and swirl to coat, then add the crushed garlic and bruised chillies immediately, before the oil has a chance to cool the wok, so their fragrance blooms in seconds rather than minutes. Stir once or twice — 5 seconds — the garlic will be fragrant but not yet coloured.
3
Add the pak boong stems first and leave them undisturbed for a count of ten before adding the leaves, so the stems, which need longer, have a head start while the leaves go in with just enough time to wilt at the edges. This is where the dish lives or dies: toss the wok with a sharp upward motion to allow the oil to briefly contact the flame — the resulting flare produces the smoky, faintly charred note that defines fai daeng, and without it there is no red fire, only steamed morning glory. The total cook time from this point is 45–60 seconds.
4
Add the tao jiew and oyster sauce directly onto the hottest part of the wok base as the vegetables fall back down, so the sauces catch on scorching metal and concentrate in an instant rather than stewing the greens. Toss once more to distribute — the leaves must be wilted and darkened at the edges, the stems must still resist the tooth; if the stems have gone limp, the dish is overcooked.

5
Transfer immediately to a warmed plate, since pak boong continues to cook in its own residual heat and becomes unacceptably soft within two minutes of leaving the wok. Serve at once.

Quality Hierarchy
01
Reserve — Pak boong pulled from a canal-side garden the same morning, cooked on a jet-burner wok station with rendered lard; tao jiew from a small-batch Thai fermentary.
02
Estate — Fresh pak boong from an Asian market, stems young and hollow; good-quality Thai tao jiew and oyster sauce; peanut oil on the hottest domestic burner available, wok pre-heated 5 minutes.
03
Market — Fresh pak boong; standard supermarket oyster sauce and yellow bean paste; vegetable oil; domestic gas burner at maximum.
04
House — Pak boong that has spent a day in the refrigerator; substitute water spinach variety where Ipomoea aquatica is unavailable; any neutral oil. The fai daeng flare will be reduced or absent; the result is a competent garlic stir-fry, not fai daeng.

Sensory Tests
◇Sight. The oil catches the flame visibly during the toss — a brief upward flare; the leaves show dark, slightly charred edges.
◇Smell. A distinct smoky, wok-breath note (wok hei) rises the moment the flare occurs — absence of this smell indicates insufficient heat.
◇Touch. Stems pressed between thumb and finger yield slightly but spring back; they must not be flaccid.
◇Sight. Leaves are fully wilted and glistening with sauce; no raw, bright-green rigidity remains in the leaf portions.
◇Where it lives or dies. The dish is decided when the oil contacts the open flame during the toss — without that flare there is no char, no smoke, and no fai daeng.
