Who is this for?

Solo cooks with induction-ready pans

If you blanch small portions in a magnetic-based saucepan, check its diameter against the induction hob’s stated range before choosing a compact single ring.

Cooks with limited worktop space

If the extra cooking zone needs to be put away after use, compare each appliance’s dimensions and weight as well as its controls.

Cooks keeping their existing pans

If your saucepan does not have a magnetic base, consider a conventional electric hot plate rather than assuming it will work on induction.

What matters when choosing?

Single-zone induction hob

Choose it when: You have a flat, magnetic-based saucepan that fits the model’s supported pan-size range and want adjustable heat on a portable ring.

Trade-off: A non-magnetic pan will not work, and a small pan may fall below the hob’s minimum supported diameter. Tefal UK specifies 12–26 cm induction pans for its IH210840; check the range for any other model separately.

Conventional electric hot plate

Choose it when: Keeping a non-induction saucepan usable matters more than choosing induction. The Daewoo SDA1731 is listed as a cast-iron electric hot plate with dial control.

Trade-off: Check that the saucepan sits stably on the heating plate, and let the plate cool before moving or storing it.

Concern What to check Who this matters to
Controlling a small boil Compare documented heat settings, timer controls and supported pan sizes, not maximum wattage alone. When I blanch one portion, I want to adjust the heat after the water boils without relying on a full-size cooker. Around 50% of consumers put controllable boiling first.
Using current cookware Test the saucepan base with a magnet and check its size against the chosen hob or plate. Replacing my non-magnetic saucepan just to blanch greens would change what I need to buy. For around 30% of consumers, keeping their cookware usable is the primary concern.
Worktop and storage Check appliance dimensions and weight, the required clearances and access to a suitable socket. If I have little counter space, the ring needs a clear place to use it and somewhere to go once it has cooled. Compact, safe setup comes first for around 20% of consumers.

Buying pitfalls

  • Buying induction before checking the saucepan

    Electrolux UK says induction cookware needs a magnetic base. Pan size matters too: Tefal UK specifies a 12–26 cm range for the IH210840, which should not be assumed for other hobs.

    Test your saucepan base with a magnet and check the chosen model’s stated pan-diameter range.

    If your current saucepan is unsuitable, you may need a different pan to use an induction hob.

  • Choosing by maximum wattage alone

    A wattage figure does not tell you whether an induction hob accepts your small saucepan or which heat and timer controls it offers.

    Compare the documented settings and pan-size limits for the exact model you plan to buy.

  • Overlooking the worktop and socket

    A portable hob still needs a stable, clear place away from water and items that could catch fire. Leicestershire Fire and Rescue Service advises avoiding extension leads for high-powered kitchen appliances and using a one-plug-one-socket approach.

    Check the appliance instructions and clearances, and plan a suitable socket arrangement before use.

  • Leaving a short blanch unattended

    A timer can help you keep track of cooking, but it does not supervise a pan of boiling water. Devon and Somerset Fire and Rescue Service advises switching appliances off after use and never leaving the house while cooking is on.

    Stay nearby as the water heats and the vegetables blanch, then switch the appliance off and let hot parts cool before storage.

Brands to consider

Tefal

Tefal offers the IH210840 Everyday Slim single-zone induction hob for an additional cooking space.

  • Tefal UK states that this model has a 45 mm profile, manual settings from 300 W to 2100 W, a timer, pause control and a 12–26 cm compatible-pan range.
  • Those details apply to the IH210840, not every Tefal hob; it still needs induction-compatible cookware.

Daewoo

Daewoo has both a single induction model and a separate conventional electric hot plate to compare for this task.

  • Nine power levels and a timer are listed for the SDA2771GE induction hob; the SDA1731 is described as a 1500 W cast-iron hot plate with dial control.
  • The models use different heating methods. Check cookware suitability and the individual model’s controls rather than transferring features between them.

Judge

Judge’s JEA90 is a portable induction option with selectable temperature settings.

  • Judge UK specifies 10 temperature choices from 60°C to 240°C, dimensions of 31 cm by 27 cm by 5 cm and a weight of 2.4 kg for the JEA90.
  • It requires induction-compatible cookware; confirm that your small saucepan is within the model’s supported size range.

VonShef

VonShef offers a single induction hob with stated power and temperature adjustments.

  • VonShef states power settings from 200 W to 2000 W, temperature settings from 60°C to 240°C, touch controls and a timer for this model.
  • VonShef advises checking that the pan is induction-compatible before purchase.

Frequently asked questions

Will my small saucepan work on an induction hob?

It needs a magnetic base and must fit the particular hob’s supported pan-size range. Electrolux UK recommends checking the base with a magnet; Tefal UK specifies 12–26 cm induction pans for the IH210840, but other models may differ.

Can I blanch greens on a conventional electric hot plate?

Yes, a conventional hot plate is an option if your saucepan is not induction-compatible. The Daewoo SDA1731 is described as a cast-iron electric hot plate with thermostatic dial control; check that your pan sits stably on the plate and follow the appliance instructions.

Should I use an extension lead for a portable hob?

Plan to use an appropriate wall socket rather than routinely relying on an extension lead. Leicestershire Fire and Rescue Service advises avoiding extension leads for high-powered kitchen appliances and using a one-plug-one-socket approach; follow the hob’s electrical instructions.

Do I need to watch the hob while blanching vegetables?

Stay nearby while the water heats and the vegetables blanch; a timer does not replace supervision. Devon and Somerset Fire and Rescue Service advises never leaving the house while cooking is on and switching appliances off when finished.
