Sliced beef, rapidly stir-fried with a large quantity of garlic and fresh green or black peppercorns — seasoned with oyster sauce, fish sauce, and dark soy sauce, finished with fresh coriander. Nuea phad kratiem is a Thai-Chinese preparation — one of the simplest and most direct of all Thai wok preparations, demonstrating the principle that correct wok temperature and good beef produce a dish that requires nothing else. The garlic is the dominant aromatic; the green peppercorns provide a sharp, fresh heat entirely different from the dried chilli heat of most Thai preparations.
**The beef:** Sliced very thin (3mm) across the grain — flank steak or skirt steak, partially frozen for easier slicing. Thin slicing is essential: it allows the beef to cook completely in the 2 minutes available in a wok without toughening. **The garlic:** A large quantity — 8–10 cloves, thinly sliced rather than minced. Sliced garlic provides a different aromatic than minced or pounded garlic: its cell walls are cut rather than crushed, producing a milder, more slowly released aromatic that can tolerate slightly longer wok exposure without burning. **The peppercorns:** Fresh green peppercorns (on the stalk) or black peppercorns, cracked — both are correct, providing different pepper profiles. Fresh green: sharp, vegetal, bright pepper heat. Black: deeper, more complex. White pepper: never, in this dish. **The preparation:** 1. Wok at maximum heat. Generous oil. 2. Add sliced garlic. Toss — allow to begin to colour (30 seconds) without burning. 3. Add the beef slices. Spread in the wok. 30 seconds without moving. 4. Toss. 30 seconds more. 5. Add peppercorns, oyster sauce, fish sauce, dark soy sauce. 6. Toss 30 seconds. 7. Remove from heat. Scatter fresh coriander. 8. Total wok time: approximately 2 minutes from garlic to plate. Decisive moment: The garlic at the beginning — 30 seconds of high heat turns raw garlic to fragrant, beginning-to-colour garlic. This is the aromatic foundation of the dish. 45 seconds: the garlic is golden and fragrant at its peak. 60 seconds: it begins to darken and the first bitter note enters. The beef goes in at 30–35 seconds — at the peak of the garlic's aromatic expression. Sensory tests: **Smell — garlic at peak aromatic:** The garlic at 30 seconds in hot oil smells of allicin (sharp, fresh, pungent garlic) transitioning to the more complex, nut-sweet note of beginning-to-Maillard garlic. This smell is the signal to add the beef immediately.
