Stir-Frying & Wok Hei

This is the chapter everything so far has been building toward — the cleaver's own bias cuts (Chapter 2), aromatics bloomed in seconds (Chapter 3), and velveted meat (Chapter 4) all exist specifically to survive genuinely extreme, genuinely fast heat.

Mise en Place: Even More Critical Here

French Cookery's own mise en place chapter warns that several French techniques can't pause mid-cook. A real stir-fry is more extreme still — once the wok is genuinely hot, there is zero time to stop and slice anything. Everything must already be prepped, portioned, and arranged before the burner even goes on.

Getting the Wok Properly Hot

1. Heat the empty wok until it's genuinely smoking Heat the empty wok on your highest burner setting until it's visibly smoking — a real, more extreme standard than the "hot pan" a Western sauté asks for.
2. Add oil, and let it heat for a few seconds Add oil once the wok is smoking, swirling it to coat the surface, and give it just a few seconds to heat through before anything else goes in.

The Order of Ingredients

1. Aromatics first, for seconds only Ginger, garlic, and scallion whites (Chapter 3) go in first, stirred constantly until just fragrant.
2. Velveted protein next Add the par-cooked meat (Chapter 4), tossing to reheat and finish cooking it through.
3. Vegetables, hardest first Add vegetables in order of hardness — firmer vegetables first, more delicate ones later — so everything finishes at roughly the same moment.
4. The pre-mixed sauce, then toss to coat Pour in the sauce bowl you prepared ahead of time, tossing everything to coat evenly and let the cornstarch slurry thicken it almost instantly.
5. Scallion greens, right at the very end Stir in scallion greens (Chapter 3) in the final few seconds, or scatter them on top as a garnish once plated.

What Wok Hei Actually Is

Wok hei — "breath of the wok" — is the smoky, slightly charred aroma real restaurant stir-fry carries. It develops when food briefly contacts the scorching-hot metal of a well-seasoned wok, and tiny droplets of oil and sauce flash against that surface, momentarily charring and depositing real, complex smoky flavour compounds onto the food.

A few real habits help close the gap:

• Use your highest heat setting, and genuinely let the empty wok smoke before oil goes in.
• Never crowd the wok — exactly Sautéing's own French Cookery warning, applied here too. A crowded wok drops in temperature and steams instead of searing, which kills any chance of real wok hei forming at all.
• Work in smaller batches if a recipe makes more than your wok and your stove's own heat output can comfortably handle at once.
• Use a genuinely seasoned carbon steel wok (Chapter 1), not a non-stick one — the bare metal surface is part of what makes the charring reaction possible.
