Choose a single-zone induction hob for lemon curd if your saucepan is induction-compatible, its base fits the hob’s specified range, and you have a safe place to use and store the appliance. Prioritise a usable low manual setting over maximum wattage: a slim model helps where storage depth is tight, while a lower stated minimum setting gives you another option to compare for gentle heating. Neither feature replaces continuous stirring or, when using a bain-marie, keeping the bowl above the simmering water.
If you make lemon curd in a small saucepan or a bowl set over simmering water, low manual heat matters more to you than a rapid-boil setting. The National Federation of Women’s Institutes’ method calls for the bowl to stay clear of the water and for continuous stirring.
If you need an extra cooking zone rather than a permanent cooker replacement, check where the hob can stand during use and whether it fits away afterwards. Tefal describes its IH210840 as 45 mm thick, but thickness alone does not tell you its full storage footprint.
If you already have a pan for lemon curd, check its induction compatibility and base diameter before choosing an induction hob. The permitted base-size range varies by model.
Start with the saucepan you intend to use, then compare low manual heat control and the space available for safe placement and storage. If that saucepan is not induction-compatible and you want to keep it, consider a non-induction portable hotplate instead, checking its controls and instructions on the specific model.
| Concern | What to check | Who this matters to |
|---|---|---|
| Gentle heat control | Compare the lowest manual setting and selectable levels, not just maximum wattage. Tefal states 300–2100 W for the IH210840; VonShef states 200–2000 W for its single induction hob. | If I am stirring a small batch over simmering water, I want to adjust the heat without relying on a rapid-boil mode. Around 42% of consumers put gentle control first. |
| Placement and storage | Measure the usable worktop and cupboard space against the hob’s full dimensions; allow for placement that follows its instructions. Tefal states that the IH210840 is 45 mm thick. | With little room to leave an extra hob out, I need one I can position safely for cooking and put away afterwards. Around 33% of consumers prioritise space and storage. |
| Cookware fit | Check that the pan is induction-compatible and measure its base rather than its rim. Tefal specifies 12–25 cm bases for the IH201840; Morphy Richards specifies 12–20 cm for its portable single induction hob. | If I want to keep my existing saucepan, I need to know it will work before choosing an induction model. Around 25% of consumers make cookware compatibility their primary concern. |
Induction requires compatible cookware, and a pan’s rim diameter may differ from the base diameter used in a hob’s stated range.
Check for an induction symbol or a magnetic base, then measure the base against the range specified for the model. If you plan to use a bowl over a pan, it is the pan beneath the bowl that must work with the induction hob.
A high-power setting helps with rapid heating but does not tell you how much manual control you have at the low end. The National Federation of Women’s Institutes’ lemon-curd method uses simmering water and continuous stirring.
Compare the lowest stated manual setting and selectable levels. For a bain-marie, adjust the hob to maintain simmering water while keeping the bowl above the water.
A portable hob still needs a stable, heat-resistant place to stand. Damage to its electrical parts or ceramic surface also changes whether it can be used safely.
Follow the model’s placement and ventilation instructions, keep water away from the appliance, and stop using it if the cord, plug or cooking surface is damaged. Tefal’s user guidance says to switch off immediately if the surface cracks.
Choosing a hob does not determine how the finished curd should be stored. Storage instructions depend on the recipe and handling method.
Follow the recipe’s jar preparation and refrigeration instructions. For its lemon-curd recipe, the National Federation of Women’s Institutes calls for hot sterilised jars and refrigeration after cooling.
Tefal lists the IH201840 and the slimmer IH210840 as portable single-zone induction options.
Morphy Richards offers a portable single induction hob with stated dimensions of H6.3 × W28 × L32 cm.
VonShef’s single induction hob is an option for comparing stated low-end manual settings.
This portable induction model is relevant if you want a movable extra cooking zone for lemon curd and can use an induction-compatible pan. Check its lowest manual setting, pan-base fit and dimensions against your own setup before choosing it.

For a movable extra cooking zone, this induction hob offers 10 power settings. Its 2000 W rating does not establish the lowest setting, so check that setting before relying on it for gentle curd cooking.
The product name also specifies touch controls, six functions, a glass panel and a safety lock. Check your saucepan’s induction compatibility and base fit, as well as the hob’s dimensions for your intended space.
Start with a low manual setting rather than a rapid-heating mode. For a bain-marie, the National Federation of Women’s Institutes’ method calls for the bowl to sit above, not in, simmering water and for the mixture to be stirred continuously.
It will work only if it is induction-compatible and its base fits the chosen hob’s specified range. Tefal states 12–25 cm for the IH201840, while Morphy Richards states 12–20 cm for its portable single induction hob; VonShef advises checking underneath the pan for an induction symbol.
Do not leave the curd unattended: the National Federation of Women’s Institutes’ method calls for continuous stirring. Set the portable hob on a flat, stable, heat-resistant surface and follow its instructions on ventilation and cleaning.
Follow the storage directions for the recipe you use. For its lemon-curd recipe, the National Federation of Women’s Institutes directs cooks to use hot sterilised jars, refrigerate the curd after cooling for up to two weeks, and consume it within three days of opening; those timings are specific to that recipe.
