Wide flat rice noodles stir-fried at extreme heat in dark soy sauce and sweet black soy sauce with egg, Chinese broccoli (gai lan), and pork, chicken, or beef — a preparation whose flavour is almost entirely dependent on the wok's temperature and the caramelisation of the dark soy sauce against the wok surface (wok hei). Pad see ew is simpler in composition than pad thai but more demanding in execution — the noodles are wide, prone to sticking, and the dark soy sauce burns rapidly. The correct result is sweet-savoury, slightly smoky, with caramelised noodle surfaces.
**Ingredient precision:** - Noodles: fresh wide rice noodles (sen yai — approximately 2cm wide), if available. Dried wide rice noodles soaked in cold water for 30 minutes otherwise. - Dark soy sauce (si-ew dam): thick, sweet, molasses-forward — the primary flavouring. Not regular light soy (which is saltier and thinner). Not Thai fish sauce. - Sweet black soy sauce (si-ew wan): a sweeter, slightly thicker version — used in combination with the dark soy. - Oyster sauce: 1 tablespoon — adds depth and umami. - Chinese broccoli (gai lan): both stems (cut into 4cm pieces) and leaves. The stems go in first; the leaves go in last (30 seconds before service). **The preparation:** 1. Maximum wok heat. Oil. Add garlic. Stir-fry 10 seconds. 2. Add protein. Stir-fry until browned. 3. Push protein to side. Add egg to the cleared space. Allow to begin setting. 4. Add the noodles. Immediately: the noodles contact the hot wok surface and begin to develop colour. 5. Add the combined dark soy, sweet soy, and oyster sauce. Toss. 6. Add Chinese broccoli stems. Continue tossing. 7. Add broccoli leaves. 30 seconds. 8. Serve immediately. Decisive moment: The moment the soy sauce hits the wok surface — at maximum temperature, the dark soy begins to caramelise and smoke immediately. This caramelisation is the flavour of pad see ew: the Maillard products of the soy sauce's amino acids and sugars at extreme temperature produce the characteristic slightly bitter, deeply savoury, slightly smoky flavour. At lower temperature: the soy sauce does not caramelise — it merely coats and moistens the noodles without developing any character. Sensory tests: **Smell:** Dark soy hitting a very hot wok produces an immediate, dramatic smell of caramelisation — a roasted, slightly sweet-bitter note that is completely different from soy sauce at room temperature. If no caramelisation smell occurs: the wok was not at temperature. **Sight:** Correctly cooked pad see ew: the noodles have developed a slight char from the wok contact. The soy sauce has caramelised to a dark, slightly sticky coating on each noodle. The broccoli leaves are wilted but still vivid green.
— **Sticking noodles:** Fresh rice noodles that have been refrigerated will be stiff and tear rather than separating in the wok. Separate them gently at room temperature before cooking, or briefly microwave to soften. — **Pale, understated flavour:** Insufficient dark soy caramelisation — the wok was not hot enough. This preparation is more sensitive to wok temperature than pad thai.
