Wok hei: the smoky wok flavor
Wok hei means "breath of the wok." It's the smoky, savory taste of food seared on blazing-hot metal, where it browns in seconds and tiny oil droplets catch the flame. A lukewarm wok just boils vegetables in their own water.
Cook small batches at home
Home stoves are far weaker than restaurant burners, so extra food cools the pan. Preheat until a drop of water vanishes at once, then cook small, dry batches. Water holds the pan near 100°C (212°F), too cool to brown.
Test yourself
Questions from the interactive lesson, with the answer and the why.
What does wok hei mostly come from?
Very hot metal browning food in seconds. Fast searing builds browned, smoky flavor.
True or false: A bigger batch gives more wok hei, because there is more food to char.
False. A big batch cools the wok and releases water, so the food steams instead of searing.
What went wrong? You tip still-dripping broccoli and a whole pound of chicken into a warm wok. Everything turns gray and soupy.
Water and a crowded pan cooled the wok, so the food steamed. Water holds the pan near 100°C (212°F), which is too cool to brown.
Fill the blank: Wet vegetables release water that holds the wok near ___ and stops browning.
Wet vegetables release water that holds the wok near 100°C (212°F) and stops browning. Water boils at 100°C, which caps the pan temperature while liquid remains.
You cook on a weak home burner. Which habit gives the best sear?
Cooking small batches of dry food. Each small batch leaves the pan hot enough to brown.
