Thai — Stir-Fry & Wok Techniques

Kuay tiew kua gai is a Bangkok street food noodle preparation — fresh wide rice noodles (sen yai) stir-fried dry with chicken, egg, and minimal seasoning until caramelised and slightly chewy, with no sauce added. This dish is unusual in the Thai noodle canon because it relies entirely on wok technique rather than seasoning — the only flavourings are a small amount of oil, oyster sauce, and white pepper. The result depends entirely on the skill of the wok cook: the noodles must caramelise without burning, the egg must set without hardening, and the chicken must be just-cooked. This is one of the purest demonstrations of wok technique in Thai cooking.

Pad cha is a fiercely aromatic stir-fry built on fingerroot (krachai, Boesenbergia rotunda), green peppercorns on the vine, fresh chillies, holy basil, and kaffir lime leaf. It is applied almost exclusively to seafood — whole fish, squid, prawn, or shellfish — and produces an intensely fragrant, slightly peppery result that the floral, medicinal krachai uniquely achieves. The dish is named for the sound of the ingredients hitting the wok (cha = the sizzle-splash sound). Krachai julienned into thin strips is the signature textural element — it should be visible and slightly crispy. The heat level is high; this is not a mild stir-fry.

Pad kee mao (drunkard's noodles) is the spicier, more aromatic cousin of pad see ew — it uses the same wide fresh rice noodles but adds fresh bird's eye chillies, holy basil (krapao), and sometimes grachai (fingerroot) to the mix. The 'drunken' name is often explained as either the hangover cure quality of the high-chilli-high-aromatic combination, or more colourfully, as the kind of thing a drunk person might throw together from available ingredients. In practice, it is one of the most flavour-intensive Thai noodle preparations — hot, herby, charred, and deeply savoury. Seafood (prawn + squid) or chicken are the standard proteins.

Pad krapao is the most-eaten single dish in Thailand — available at every restaurant from street stall to hotel, eaten at any time of day, and considered the ultimate benchmark of Thai wok cooking. Its simplicity is deceptive: it requires extreme wok heat, fresh holy basil (krapao), and a high quality protein-to-flavour ratio to achieve the characteristic dry-wok char and the peppery basil finish. Minced pork (moo) or chicken (gai) is the traditional standard; the wok must be at maximum heat; the holy basil goes in at the absolute last moment and is served immediately. The fried egg on top (kai dao) is not optional in the Thai street tradition — pad krapao without a fried egg is considered incomplete.

Pad med mamuang (cashew stir-fry) is a mild, sweet-savoury Thai stir-fry that is both extremely popular internationally and frequently misrepresented by excessive sweetness. The key technique is separately deep-frying the cashews until golden before adding to the stir-fry — raw cashews added directly to the wok go soft; pre-fried cashews maintain crunch. The sauce is oyster sauce, fish sauce, a small amount of dark soy, and a moderate amount of palm sugar. Dried red chillies (prik haeng) are deep-fried alongside the cashews for colour and mild heat. The chicken (sliced breast or thigh) should be the freshest possible to handle the relatively simple sauce without any off-flavour contamination.

Pad prik king is a dry, intensely fragrant stir-fry of pork (typically belly), tofu, or long beans with a red curry paste base and kaffir lime leaf chiffonade — essentially a curry paste stir-fried without coconut milk. The paste is fried in oil until completely fragrant and the fat separates, then the protein is added and cooked in the paste rather than in coconut milk. The absence of coconut milk produces a more concentrated, direct paste flavour. Kaffir lime leaves (fine chiffonade) are the defining finish. This dish demonstrates that curry paste has a life outside of coconut curry.

Pad see ew (stir-fried with soy sauce) uses fresh wide rice noodles (sen yai) that must be fresh, not dried, for the correct result. The noodles go in with the proteins and receive direct wok-metal contact that chars the edges and caramelises the dark soy coating — the 'wok hei' effect applied to a flat noodle. Dark soy sauce is the primary seasoning, providing colour and caramelisation; oyster sauce adds sweetness and body; light soy for salinity. The key technique is allowing the noodles to sit flat on the wok surface and char before breaking them apart — this produces the characteristic caramelised edges that define pad see ew from soggy, steamed noodles. Chinese broccoli (gai lan) is the traditional vegetable.

The technique of pad thai is a precise sequence — not a recipe, but a choreography. Dried sen lek (thin rice noodles) are soaked until pliable (not fully cooked), then go into the wok with shrimp, tofu, and the pad thai sauce (tamarind-palm sugar-fish sauce, pre-mixed and reduced). The egg is pushed to one side and scrambled separately before being folded through the noodles. Bean sprouts and garlic chives are added at the end for raw crunch. The noodles must caramelise against the wok bottom between each stir — constant movement prevents the char that distinguishes great pad thai from steamed noodle soup.

Phat king (ginger stir-fry) is a Chinese-Thai preparation — sliced chicken and julienned ginger with wood ear mushrooms (hed hunu), spring onion, and oyster sauce. The ginger is julienned into matchsticks and stir-fried with the protein, providing both flavour and a pleasant chewiness when cooked. Unlike Thai dishes where ginger is a background aromatic, in phat king the ginger is a primary texture and flavour element. The dish demonstrates the Chinese culinary heritage of Bangkok Thai cooking — it uses no curry paste, no fish sauce as primary seasoning, and relies instead on oyster sauce, light soy, and sesame oil as the flavour architecture.

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.

Phat phak ruam is not a single dish but a technique — the art of stir-frying mixed vegetables to achieve the correct texture for each element while maintaining a unified sauce. The Thai approach to vegetable stir-fry involves cooking more delicate vegetables (morning glory, Chinese spinach, bean sprouts) for under 60 seconds total, and harder vegetables (broccoli stems, baby corn, carrot) for 2–3 minutes before the softer elements are added. Garlic and oyster sauce are the minimal flavouring base. The wok must be scorching — the vegetables should 'jump' rather than steam, and slight charring of the leaf edges is correct.

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.

Rad na (poured-face) is the Thai noodle dish with a thick cornstarch-thickened gravy — wide fresh rice noodles or egg noodles are wok-fried until charred, then topped with a poured gravy of Chinese broccoli (gai lan), protein (typically pork, prawn, or mixed seafood), oyster sauce, fish sauce, and chicken stock thickened with tapioca starch. The contrast between the charred, slightly crispy noodle base and the silky, glossy gravy is the technique's payoff. Getting the starch ratio correct is the critical skill — under-thickened produces a watery sauce; over-thickened produces a glue-like result that overwhelms the noodles.

Tofu stir-fry in Thai cooking is distinctly different from Chinese mapo tofu or Korean sundubu jjigae — the Thai approach uses firm or silken tofu as a secondary protein, fried briefly in hot oil until lightly crisped on the outside, then combined with the standard wok sauce base of oyster sauce, fish sauce, and garlic. Thai tofu preparations are generally simpler than Chinese ones — the tofu is primarily a protein supplement in dishes like pad krapao tofu or a textural element in gaeng jeud (clear vegetable soup). For the dedicated tofu stir-fry, the pre-frying step is essential: deep-fried firm tofu that has developed a golden, slightly chewy skin integrates differently into stir-fry preparations than raw tofu.
