Sauce makers who need gentle control
If you make roux-, milk- or cheese-based sauces, you may want settings that let you reduce the heat while you stir. A timer can help you keep track of cooking, but it does not replace watching the pan.
Who this choice affects
For a one-pan cheese sauce, the useful starting point is your saucepan and the space available to cook and let the hob cool afterwards.
Shared-house cooks using existing pans
If you plan to use a saucepan already in the kitchen, its base may decide the type of hob you can buy. Induction needs a magnetic base; a conventional cast-iron hot plate does not have that particular restriction.
Space- and socket-conscious flatmates
If the worktop, sockets and storage space are shared, consider where the hob and lead will sit during cooking and where the appliance can cool without getting in anyone else’s way.
What to check before choosing
Check the saucepan before comparing controls: an induction hob cannot heat it properly unless the base is magnetic. Then decide whether one ring is enough and where the appliance can be used safely.
Single-zone induction hob
Choose it when: Your saucepan has a magnetic base within the model’s stated size range and you want a choice of heat settings while making sauce.
Bear in mind: A non-magnetic pan will not heat properly, and the pan and hob surface can still be hot after cooking.
Single cast-iron hot plate
Choose it when: You need to use a saucepan that is not suitable for induction and only need one cooking zone.
Bear in mind: The cast-iron plate retains heat after switch-off, so allow space and time for it to cool.
Double hot plate
Choose it when: You regularly make the sauce while heating something in a second pan.
Bear in mind: Two rings take up more worktop space and can draw more power when used together; they add little to a one-pan task.
| Concern | What to check | Who this matters to |
|---|---|---|
| Adjustable heat | Compare the lowest stated setting and the available manual controls; do not judge sauce control by maximum wattage alone. | If I need to lower the heat while stirring cheese sauce, I want controls I can adjust rather than relying on a preset. Around 27% of consumers put gentle sauce control first. |
| Existing saucepan | For induction, test whether a magnet sticks firmly to the base and check its diameter against the model’s stated range. | I want to use the shared saucepan without replacing it or discovering that it will not heat. Existing-pan compatibility comes first for around 27% of consumers. |
| Space and electrical safety | Allow clear, dry worktop space and check the socket arrangement and combined appliance load before use. | When others need the worktop too, I need room for the hob, its lead and safe cooling after cooking. Around 33% of consumers prioritise shared-kitchen space and safety. |
| Two-pan capacity | Check whether you need independently controlled rings and whether both pans and the larger unit will fit. | If I heat another component while making the sauce, one ring will not serve both pans at once. Two-pan capacity is the primary need for around 13% of consumers. |
Mistakes to avoid
-
Buying induction before checking the saucepan
A non-magnetic base will not heat properly on induction, and a suitable pan can still fall outside a particular hob’s supported base-size range.
Test the base with a fridge magnet, measure it and compare it with the shortlisted model’s instructions. Tefal UK lists a 12 cm to 25 cm compatible base range for its IH201840; other models may differ.
If the existing saucepan is unsuitable, you will need access to an induction-compatible one.
-
Treating an extension block as another cooking socket
Connecting several appliances can exceed an extension lead’s rating. Electrical Safety First warns that overloading or daisy-chaining extensions can create an overheating and fire risk.
Use an accessible wall socket where practical. If an extension is necessary, check its marked rating and the total load, do not daisy-chain it, and fully unwind a cable reel where applicable.
-
Choosing two rings for a one-pan sauce
A double unit only adds useful cooking capacity if you need another pan at the same time. Otherwise it occupies more of the shared worktop and increases the potential simultaneous electrical load.
Choose the number of rings for the cooking you actually do, and check that a double unit has a suitable position and socket arrangement before considering one.
-
Overlooking water, damage and heat after use
A wet work area, damaged lead or cracked ceramic plate is a safety concern. Switching the hob off does not mean its pan or surface is immediately cool.
Keep electrical connections dry, stop using a damaged appliance and let it cool in a clear place before storing it. Electrical Safety First advises against handling electrical equipment with wet hands.
Brands to consider
These product lines illustrate the hob formats in this decision; compare the specifications of the exact model you intend to use.
Tefal
Tefal UK lists portable induction models with digital controls, multiple power settings and ceramic surfaces.
- Tefal UK states that the IH201840 has nine power levels from 450 W to 2100 W and accepts induction-compatible pan bases from 12 cm to 25 cm.
- An induction-compatible saucepan is necessary. Check the base-size range of the exact Tefal model rather than assuming every model accepts the same pan.
Duronic
Duronic lists conventional cast-iron hot plates in single- and double-ring formats.
- Duronic specifies a 1500 W, 18.7 cm ring and a heat dial for its single-ring HP1 BK.
- Its listed 2500 W double units have 1500 W and 1000 W rings, making space and combined electrical load more important if both are used.
Russell Hobbs
The Russell Hobbs Mini Hob 15199 is a double-hot-plate option for cooking with two pans.
- Russell Hobbs UK lists independently controlled 1500 W and 750 W plates for this model.
- For cheese sauce in one saucepan, the second plate is useful only if you also need to heat another pan and can accommodate the larger unit.
Joybuy induction hob options
This portable induction option is for cooks considering a single zone for cheese sauce. Check that your saucepan is suitable for induction and that the hob fits the shared cooking space.

ochama 2000W Portable Induction Hob, 10 Power Settings
A single-zone option if you have a magnetic saucepan and want settings you can adjust while making sauce.
The product name specifies 2000 W output, touch controls, 10 power settings, six functions and a glass panel.
Before choosing it for a gentle hold, check its lowest setting and compatible pan-base diameter. Check the appliance rating against the available socket arrangement and follow its instructions for ventilation and hot surfaces.
Common questions
Will my saucepan work on a portable induction hob?
It needs a magnetic base that fits the chosen hob’s supported size range. Tefal advises checking whether a magnet sticks firmly to the base; its IH201840 specifies a 12 cm to 25 cm pan-base range, but you should check the range for the model you buy.
Which hob controls matter when making cheese sauce?
Look for settings you can reduce while stirring, rather than choosing by maximum output alone. Tefal UK lists nine levels from 450 W to 2100 W for the IH201840 and a 300 W to 2100 W manual range for the IH210840; those specifications do not make a preset a substitute for watching the sauce.
Can I use the shared kitchen’s extension lead?
Only if its marked rating and the combined load of connected appliances allow it. Electrical Safety First warns against overloading extension leads or connecting one extension device to another; an accessible wall socket is preferable where practical.
What if the hob has a damaged cable or cracked ceramic plate?
Stop using the appliance. Tefal’s induction instructions warn against use with a damaged cord or plug and say to switch off if the ceramic plate cracks; seek appropriate repair or replacement advice rather than continuing to cook on it.
