Gentle-sauce cooks
If you often whisk a small pan of cheese, milk or butter sauce, easy heat adjustment matters more than a headline boost setting. Which? assesses low-temperature holding as a distinct part of hob testing.
Who this is for
Small-kitchen solo cooks
If you usually cook for one, consider whether a narrow two-zone hob gives you enough room for your pans. Bosch GB identifies a plug-in four-zone model, while the product information lists a narrow Zanussi model that requires hardwiring: size and connection type are separate decisions.
Kitchen upgraders with fixed electrics
If you are replacing a built-in hob, compare the new appliance with the existing worktop opening, space beneath it and electrical supply. AEG UK advises checking the cut-out and connection requirements before installation.
What matters when buying
For one saucepan, start with pan compatibility and gentle-heat control; then decide how much worktop space and cooking capacity you need. A plug-in label applies to a particular model, not to induction hobs generally.
Compact built-in hob
Choose when: A narrow worktop or existing domino-sized opening matters more than having four zones; The product information lists the Zanussi ZITN320X as a 29 cm, two-zone example.
Trade-off: That Zanussi model requires a dedicated 30 or 32 Amp hardwired circuit, despite its compact width.
Plug-in four-zone hob
Choose when: You want a four-zone layout and an exact model identified for plug-in use, such as the Bosch PUG61RAA5B, which Bosch GB calls Plug & Play.
Trade-off: Four zones exceed what one sauce needs, and you must still check the model instructions, worktop fit and suitable electrical supply.
Hardwired four-zone hob
Choose when: You also want separate zones for other pans and have a suitable built-in installation. The product information lists the four-zone Indesit IS 83Q60 NE as one example.
Trade-off: That Indesit model is 59 cm wide and requires a dedicated 32 Amp hardwired circuit; its extra zones do not establish better low-heat control.
| Concern | What to check | Who this matters to |
|---|---|---|
| Gentle heat | Check whether you can lower the setting quickly while stirring, and look for an exact-model simmering test where available. Which? assesses low-temperature holding separately. | If my sauce thickens quickly, I need to turn the heat down without losing my place while whisking. Around 36% of consumers put gentle-heat control first. |
| Kitchen fit | Compare the worktop cut-out and available depth with the model’s installation instructions; confirm its connection method and electrical requirements. | A narrow worktop or an existing hob opening limits which appliance I can install. For around 29% of consumers, space and installation fit are the primary concern. |
| Useful features | Compare the zones you would use and the exact model’s timer, residual-heat indication and child lock, rather than assuming every hob includes them. | When I usually cook one portion, I want the functions I will use rather than extra zones for their own sake. Useful everyday features come first for around 21% of consumers. |
| Control style | Choose between touch controls and dials after checking the exact model’s layout and how readily you can change a setting while stirring. | If I am whisking continuously, I want controls I find straightforward to operate. Around 14% of consumers prioritise the control style. |
Buying pitfalls
-
Assuming every induction hob simmers alike
A boost function or a long list of power levels does not demonstrate steady low-temperature cooking. Which? tests whether a hob can maintain a very low temperature, an important distinction for a sauce that needs close attention.
When sauce is your main use, seek an exact-model simmering assessment where available and check that you can adjust the controls promptly while whisking.
-
Choosing a built-in hob by surface width alone
The appliance must fit the opening and the space beneath it, and its electrical requirements must suit the kitchen. The product information lists dedicated hardwired circuits for the Zanussi ZITN320X and Indesit IS 83Q60 NE; AEG UK advises checking the cut-out before installation.
Compare the exact model’s installation instructions, cut-out, depth and connection requirements with your kitchen, and arrange a qualified installer where required.
A different opening or unsuitable circuit may mean worktop or electrical work before the hob can be installed.
-
Overlooking the saucepan base
Induction needs a ferromagnetic pan base. Bosch GB also advises matching the base to the cooking zone, so a saucepan’s overall rim width is not enough to establish small-pan suitability.
Check that a magnet is attracted to the base and compare its base size with the exact hob’s pan requirements.
If your current saucepan is unsuitable, you may need induction-compatible cookware.
-
Relying on the timer instead of watching the sauce
A timer and residual-heat indicator can provide reminders, but they do not keep a thickening sauce from catching or make the surface safe to touch immediately after cooking.
Keep stirring and monitoring the pan, and keep combustible items away from the hob. Cambridgeshire Fire and Rescue Service advises against leaving pans unattended.
Brands to consider for these hob layouts
Bosch
Bosch GB identifies both a conventional four-zone model and a separate four-zone model labelled Plug & Play.
- The PIE631BB5E has four zones, TouchControl, PowerBoost, QuickStart, Restart and ChildLock, according to Bosch GB.
- The Plug & Play designation belongs to the PUG61RAA5B; it does not establish the connection type or simmering performance of other Bosch models.
Zanussi
The ZITN320X is a narrow built-in option for a kitchen where a full-width hob would take up too much worktop space.
- The product information lists this model as 29 cm wide with two zones, front dials, pan detection, a combined zone and residual-heat indicators.
- The same listing requires a dedicated 30 or 32 Amp hardwired circuit; narrow does not mean plug-in.
Indesit
The IS 83Q60 NE represents a conventional four-zone layout for cooking with more than one pan.
- The product information lists four independent zones, 9+ power levels, individual timers, a child lock and residual-heat indicators for this model.
- This 59 cm model requires a dedicated 32 Amp hardwired circuit; its listed features do not establish how it performs when simmering sauce.

IAGREEA DF200-14V10 portable induction cooker, 2000 W
Consider this portable cooker if you want a cooking surface for one pan rather than a built-in worktop installation.
The product name lists eight power levels, temperature settings of 60–270°C, a three-hour timer and suitable cookware diameters of 12–26 cm. Those settings do not establish how steadily it holds a gentle simmer; check its fitted plug and connection requirements before buying.
No image available
CIARRA CBBIH292T 29 cm two-zone induction hob
Consider this built-in model when worktop width is the main constraint and two zones are enough for your cooking.
The product name lists a 2900 W rating, touch controls, nine power levels, a timer and a child safety lock. Check the exact cut-out and electrical connection requirements before choosing it; its power levels alone do not establish simmering performance.
No image available
Ciarra 60 cm four-zone built-in induction hob
Consider a four-zone layout if you expect to cook other dishes alongside a small saucepan; the extra zones are not needed for the sauce itself.
The product name specifies a 60 cm built-in design with modular power control. Check the zone’s small-pan requirements, worktop cut-out and exact electrical connection before ordering.
No image available
Bosch PIE631BB5E Series 4 60 cm induction hob
Consider this four-zone built-in model if a hardwired installation suits your kitchen and you also cook with other pans.
Bosch GB lists four zones and TouchControl for the PIE631BB5E; the product name specifies a hardwired connection. Check the cut-out, circuit and minimum suitable pan base in the model instructions. Its controls do not, by themselves, establish gentle-simmer performance.
No image available
Belling ComfortCook IHT603 60 cm induction hob
Consider this model if you are looking for a wider hob rather than a narrow surface for one pan.
The product name identifies the ComfortCook IHT603 as a 60 cm induction hob. Before choosing it for a small saucepan, compare the pan base with the model’s zone requirements and check its worktop and electrical installation instructions.
Common questions
Do I need a particular saucepan for an induction hob?
Yes: the base must be ferromagnetic. Bosch GB identifies cast iron, enamelled steel and suitable stainless steel as examples; glass, clay, copper and aluminium pans will not work directly unless they have an appropriate magnetic base. Check the base size against the chosen cooking zone as well.
Will a small saucepan work for one-person cheese sauce?
It can if its magnetic base meets the exact hob’s pan-detection and zone-size requirements. Compare the base, rather than just the pan’s rim, with the minimum dimensions in the model instructions.
Can I plug a built-in induction hob into a 13 Amp socket?
Only choose that connection if the exact hob is designed for it and its instructions suit your electrical supply. Bosch GB labels the PUG61RAA5B Plug & Play; AEG UK says most other induction hobs cannot be plugged into a 13 Amp socket. The product information specifies dedicated hardwired circuits for the Zanussi ZITN320X and Indesit IS 83Q60 NE.
Should I measure the worktop opening before buying?
Yes. Compare the existing cut-out and space beneath it with the exact hob’s installation dimensions, not just its stated surface width. AEG UK advises checking both areas before arranging installation.
Does boost power help prevent cheese sauce from catching?
No: boost power is not evidence of controlled gentle heat. For cheese sauce, focus on lowering the setting promptly and on exact-model low-temperature test results where available; Which? assesses whether hobs can maintain a very low temperature without drying or hardening food.
