Fire vs. induction — what the heat actually does.

Two ways to cook the same protein. Two completely different memories.

Put the same piece of fish on two stations — one over wood, one over induction — and you will eat two different dinners. Not because the cook changed their mind, but because heat itself behaves differently depending on how it arrives.

An induction hob does not have a flame. A coil under the glass throws an alternating magnetic field; that field induces tiny eddy currents inside a ferrous pan, and the pan itself becomes the heat source. The hob stays cool. The transfer is direct, fast, and almost entirely conductive — pan to food, with very little wandering off as warm air. That precision is why induction is the quiet hero of modern pastry kitchens and tempering stations: you can hold 62°C for hours without drift.

Wood fire is the opposite kind of honest. A log burning at full song sits somewhere between 600°C and 900°C at the embers, and throws heat in three directions at once: conduction (where the metal of the grill touches the food), convection (hot air and steam moving around it), and radiation (infrared light, the same wavelengths that warm your face when you stand near a fire). Radiation is the secret ingredient. It penetrates the surface of a protein in a way hot air cannot, which is why a steak over coals develops a crust before the inside has finished thinking about cooking.

Induction asks for a dial. Fire asks for attention.

Then there is the chemistry. Above roughly 140°C, amino acids and reducing sugars on the surface of food begin the Maillard reaction — the cascade of browning that builds hundreds of new aromatic compounds, none of which existed in the raw ingredient. Induction can absolutely hit Maillard temperatures; a screaming cast-iron pan will brown beautifully. But live fire layers something on top: pyrolysis of the wood itself, which releases guaiacols, syringols and phenols. Those are the molecules the nose reads as 'smoke', 'campfire', 'bacon', 'whisky'. They land on the food, dissolve into fat, and stay.

Smoke is also why fire-cooking is a slower art. The molecules that flavour beautifully are the same ones that, in excess, turn bitter and acrid. Good fire cooking is mostly fire management — building embers, not flames; moving the food in and out of the heat; letting wood burn down before the protein ever touches the grate. Induction asks for a dial. Fire asks for attention.

Radiation is the secret ingredient — the same wavelengths that warm your face when you stand near a fire.

Neither is better. Induction gives you control, repeatability and a clean kitchen — a gift when you're holding twelve sauces at service. Fire gives you crust, smoke, and the particular drama of cooking in front of people who can see it happen. One is a scalpel. The other is a story.

At The Curio Table, both stations run side by side on purpose. The induction line handles the tempers, the emulsions, the things that need to hold. The fire handles the proteins, the breads, the vegetables that earn their character from char. The same ingredient can travel between them in a single dish — seared over wood, finished on induction, plated together. Two heats, one plate, two completely different memories laid down in the same bite.

  • Nathan Myhrvold et al., Modernist Cuisine (2011)Comparative thermodynamics of induction, gas and wood fire.
  • Maga, 'Smoke in food processing', CRC Critical Reviews in Food Science & Nutrition (1988)Guaiacols, syringols and phenols as the aromatic backbone of wood smoke.
