Why Induction Heat Control is Different

If you've switched from gas to induction, one of the first things you'll notice is how differently the heat behaves. There's no visible flame, heat response feels almost instant, and the power levels can seem abstract compared to adjusting a gas dial. But once you understand how induction heat works — and learn a few key techniques — you'll find it offers some of the most precise cooking control available.

Understanding Power Levels

Most induction hobs offer between 9 and 14 power levels, often numbered 1–9 or 1–14. These aren't arbitrary — they correspond to roughly proportional wattage outputs. For example, on a hob with a maximum zone output of 2,200W:

  • Level 1–2: Very low heat (around 100–400W) — ideal for keeping food warm, melting chocolate, or gentle hollandaise sauce.
  • Level 3–4: Low-medium heat — simmering soups, slow-cooking sauces, poaching eggs.
  • Level 5–6: Medium heat — sautéing vegetables, scrambled eggs, reducing sauces.
  • Level 7–8: Medium-high — stir-frying, browning meat, pan sauces.
  • Level 9+: Full power — rapid boiling, searing steaks, wok cooking.

Start by mapping your most common tasks to specific levels and noting what works — after a few weeks, it becomes second nature.

The Boost Function: Use It Wisely

Most induction hobs have a boost or power boost setting that temporarily pushes the zone to its maximum output — sometimes up to 3,200W or more. This is brilliant for bringing a large pan of water to the boil quickly. However, it's not designed for sustained cooking — turn it down once you've reached your target temperature or the contents will boil over rapidly.

Pan Choice Matters More Than You Think

The quality and material of your pan dramatically affects how evenly and effectively induction heat is delivered. Tips for getting the best results:

  • Use flat-bottomed pans. A warped base creates air gaps that reduce heat transfer efficiency and can cause hot spots.
  • Match pan size to zone size. Using a small pan on a large zone wastes energy and can cause uneven heating.
  • Cast iron holds heat well but is slow to respond to level changes — factor in a delay when adjusting.
  • Stainless steel with a thick base is versatile and gives excellent control across all power levels.

Simmer Control: Getting Low Temperatures Right

One of induction's genuine strengths is maintaining a very precise, low simmer — something gas hobs can struggle with at their lowest setting. For a true simmer (around 85–90°C):

  1. Bring the liquid to temperature on a medium setting first.
  2. Drop to level 2 or 3 to maintain the simmer.
  3. Use a lid to help retain heat and reduce the power needed.

If your hob keeps cutting in and out at very low settings (a cycling behaviour some entry-level induction hobs exhibit), try using a heavy-based pan — the thermal mass helps even out the heat between power pulses.

Searing and High-Heat Cooking

For a proper sear on steak, chops, or fish:

  1. Preheat the pan on high for 2–3 minutes before adding oil or food — induction heats the pan, not the air, so preheating is essential.
  2. Add a small amount of high-smoke-point oil (refined sunflower, groundnut, or avocado oil).
  3. Sear on maximum or near-maximum power. Don't move the food for the first minute — let the crust form.
  4. Reduce heat once the crust has developed to finish cooking through.

Using the Timer and Auto Features

Many induction hobs include a built-in timer that turns off a zone after a set period. Use this to:

  • Set rice or pasta to cook without watching the clock.
  • Avoid over-reduction of stocks and sauces.
  • Prevent food from burning if you're called away.

These features aren't just gimmicks — they genuinely improve cooking consistency and safety.

Practice Makes Perfect

The best way to get comfortable with your induction hob is simply to cook on it regularly and pay attention. Keep notes on what power levels worked for specific dishes, experiment with your cookware, and don't be afraid to adjust mid-cook. Induction's immediate response makes it far more forgiving than most people expect.
