Who this suits

One-pan small-kitchen cooks

You usually cook polenta in one saucepan and want to put the hob away between meals rather than give it a permanent place on the worktop.

Cooks who want simmer control

You need to heat the cooking liquid, then reduce the heat as the polenta thickens while you stir. Manual adjustment matters more to you than a high maximum setting alone.

Owners of induction-compatible pans

You already have a magnetic saucepan and can check its base diameter against a hob’s stated pan-size range before choosing induction.

What matters when choosing

Measure the clear space and check your saucepan first; then compare manual heat controls and decide whether a second cooking zone would earn its place.

Concern What to check Who this matters to
Worktop and storage space Compare the hob’s width and depth with a flat, stable space that leaves its ventilation clear; check its stored height separately. If I cook one pan at a time, I want the hob to fit securely while in use and go away afterwards. Around 36% of consumers put space first.
Adjustable simmer heat Check the lowest stated manual setting, the available adjustment steps and how the timer or presets behave. As polenta thickens, I need to lower the heat while I keep stirring. Around 29% of consumers make simmer control their primary concern.
Existing saucepan Test the base with a magnet and compare its base diameter with the chosen induction hob’s stated range. I would rather use my current polenta pan than obtain another one just for this hob. For around 21% of consumers, pan compatibility comes first.
Room for a second pan Measure the space needed for both pans and check the two-zone hob’s connection rating against its instructions. If I regularly warm a sauce or vegetables alongside polenta, I need another cooking position. That is the main concern for around 14% of consumers.

Buying pitfalls

  • Ordering induction before checking the pan

    An ordinary non-magnetic saucepan will not work on an induction hob, and a magnetic pan can still have a base outside the model’s accepted size range.

    Test the base with a magnet and measure the base, not just the rim, against the hob manual. Judge’s JEA90 manual, for example, identifies magnetic cookware as necessary and bases below 12 cm as unsuitable for that model.

  • Choosing by maximum wattage alone

    Bringing liquid to the boil is only part of making polenta; the thickening stage calls for lower, adjustable heat and continued stirring.

    Compare the manual settings at the low end of the range, and read how any timer or cooking preset operates before relying on it.

  • Squeezing the hob onto a crowded surface

    A surface that obstructs ventilation or puts a lead across the working area creates avoidable hazards, even if the hob itself fits.

    Use a flat, stable position, keep ventilation clear and keep leads and textiles away from heat. IKEA’s TILLREDA manual also says not to connect the hob using an extension cord or route its cord across working areas; follow the instructions for the model you choose and stay present while cooking.

  • Buying two zones for a one-pan routine

    A second cooking position is useful when another pan is regularly needed, but both the appliance and the pans must fit the available worktop. IKEA UK lists a 2800 W connection rating for its two-zone TILLREDA, compared with 2000 W for its single-zone model.

    If polenta is normally the only dish on the hob, measure a single-zone model first. Check a two-zone model’s dimensions and electrical instructions before choosing it for occasional extra capacity.

Brands to consider

IKEA

IKEA UK lists single-zone and two-zone TILLREDA portable induction hobs, giving one-pan cooks and those needing a second pan different formats to assess.

  • The single-zone TILLREDA measures 27 × 30.5 cm across the worktop and has a stated 2000 W zone.
  • The two-zone TILLREDA has a stated 2800 W connection rating; both formats require induction-compatible cookware.

Tefal

Tefal’s Everyday and Everyday Slim portable induction models provide single-zone options for buyers comparing storage shape and cooking controls.

  • Tefal UK states that Everyday Slim IH210840 is 45 mm thick and has manual control from 300 to 2100 W, plus pause and timer functions.
  • Check the current manual for the exact selectable settings on Everyday IH201840: Tefal’s product-page descriptions differ. A timer does not replace stirring and supervision.

Judge

Judge’s portable induction guidance is useful when checking whether an existing saucepan can be used.

  • The JEA90 manual explains the magnetic-pan requirement and identifies pan bases below 12 cm as unsuitable for that model.
  • Use the size guidance for the specific hob under consideration; it is not a pan-size rule for every portable induction model.

Common questions

Will my polenta saucepan work on a portable induction hob?

It will work only if its base is magnetic and falls within that hob’s accepted pan-size range. Test the base with a magnet, then measure its diameter and check the chosen model’s manual. Judge’s JEA90 manual, for example, identifies bases below 12 cm as unsuitable for that model.

Do I need the highest-wattage hob for polenta?

No: adjustable lower heat matters once the cooking liquid has boiled and the polenta begins to thicken. Compare manual settings rather than maximum wattage alone; Tefal UK states a 300–2100 W manual range for Everyday Slim IH210840. Keep stirring and supervising the pan instead of treating a preset or timer as permission to leave it unattended.

Can a portable induction hob go on any spare surface?

No: it needs a flat, stable position with unobstructed ventilation and a safely routed lead. Follow the chosen model’s instructions. IKEA’s TILLREDA manual says not to use an extension cord or run the cord across working areas, while Cambridgeshire Fire and Rescue Service advises keeping electrical leads and textiles away from the cooker.

What product-marking information should I check for Great Britain?

Check the listing and supplied instructions for identifiable manufacturer and safety information, and for the marking applicable to the product. The Office for Product Safety and Standards explains that electrical equipment must meet the Electrical Equipment (Safety) Regulations 2016 before being placed on the Great Britain market. Department for Business and Trade guidance dated 21 August 2026 says CE marking continues to be recognised alongside UKCA for products within that guidance’s Great Britain scope; Northern Ireland has different arrangements. A mark does not establish that a particular hob fits your pan or worktop.
