How it works
Charcoal produces a radiant heat far more intense than gas or electric hobs, reaching temperatures between 350 and 400 degrees Celsius when fully lit. This heat level is essential to achieve wok hei, the distinctive smoky, charred aroma and flavour that defines excellent stir-frying. The round-bottomed carbon steel wok sits directly over the hot coals, allowing maximum heat transfer and rapid cooking. Setting up requires a kettle grill or similar BBQ where the grate can be removed to cradle the wok securely above the coals. Using a chimney starter to get a full load of glowing embers ensures consistent, high heat. It is important to use carbon steel woks as they withstand these temperatures and develop a natural seasoning, unlike non-stick or stainless steel alternatives. Execution demands preparation and speed. All ingredients must be prepped and within reach before heating the wok, as stir-frying happens fast and waits for nothing. Cook in small batches to avoid overcrowding, which causes temperature drops and steaming rather than searing. The intense heat quickly chars and cooks food while preserving texture and flavour, resulting in vibrant, smoky dishes with that sought-after wok hei.
Best for
- stir-fries
- fried rice
- charred greens
- flash-fried noodles
- quick searing of small cuts
Common mistakes
- Overcrowding the wok causing temperature loss and steaming
- Using non-carbon steel woks that cannot handle high heat
- Starting without all ingredients prepped and ready
- Not controlling airflow leading to inconsistent heat
- Leaving the wok unattended during cooking
