Choose a single-zone induction hob if your saucepan is induction-compatible and fits the hob’s stated pan-size range; models from CASO Design and Klarstein offer adjustable settings to consider for custard that you will stir and supervise. If keeping a non-induction saucepan is the deciding factor, consider a dial-controlled solid electric hot plate instead, allowing for its hot surface after switching off and checking that your shared worktop and socket are suitable.
If you cook custard, sauces or milk-based dishes, compare the settings you can change while cooking rather than choosing an on/off burner. CASO Design, Klarstein and Judge list models with multiple power or temperature settings, though those specifications do not establish how a particular recipe will cook.
A portable hob may suit you if you need an extra cooking area that can be moved and stored. Check where it will stand and cool, and leave room to keep its cable clear of other appliances. Buckinghamshire Fire & Rescue Service advises staying with cooking and switching off the heat if you leave the room.
Your pan can settle the choice between hob types. The CASO Design ProSlim 2000 requires induction cookware within its stated 12–22 cm recognition range. If your saucepan is not induction-compatible and you do not want another pan, a solid electric hot plate avoids that induction-cookware requirement.
Consider it when: Your custard saucepan is induction-compatible, and you want to compare models with adjustable settings and a timer.
Check before choosing: Pan-size limits differ; the CASO Design ProSlim 2000 states a 12–22 cm recognised diameter, and listed settings alone do not establish how gently a recipe will heat.
Consider it when: You want to keep using a non-induction saucepan and prefer dial-controlled heat settings, as offered by the Quest model.
Allow for: The solid plate remains hot after cooking and needs a safe place to cool before storage.
| Concern | What to check | Who this matters to |
|---|---|---|
| Adjustable heat | Compare selectable power or temperature levels and whether controls can be changed during cooking. Check timer operation separately; a timer does not replace supervision. | When I make custard, I want to adjust the heat and keep stirring rather than rely on a single fixed setting. Around 46% of consumers put controllable heat first. |
| Cookware and space | For induction, check the pan material and the exact model’s permitted base size. Measure the available worktop and a safe place to store the hob. | I would rather use my current saucepan and need an appliance I can put away after it has cooled. For around 36% of consumers, cookware compatibility and fit are the primary concern. |
| Shared-kitchen safety | Check for stable, heat-resistant placement, clear cable routing and a suitable socket that is not overloaded; compare model-specific safeguards. | With other people using the kitchen, I need to avoid a crowded socket, an unstable hob and spills left on the worktop. Around 18% of consumers make shared-kitchen safety and clean-up their first concern. |
An unsuitable pan may not be detected or operate as intended. CASO Design states that its ProSlim 2000 requires induction cookware and recognises pan diameters of 12–22 cm.
Check whether your pan has an induction-compatible base, then confirm its size against the exact hob’s instructions before ordering.
If your existing saucepan is unsuitable, you may need a separate induction-compatible one.
A timer is a prompt, not someone to watch the pan. Buckinghamshire Fire & Rescue Service advises staying with cooking and turning off the heat if you need to leave the room.
Stay nearby to stir and monitor the custard; use a timer only as an additional reminder.
Electrical Safety First warns against overloading sockets and extension leads. A portable hob adds another electrical appliance to a shared kitchen where outlets may already be in use.
Use a suitable wall socket where possible, avoid daisy-chaining extensions, and stop using a lead, plug or socket that is damaged or becomes hot.
A 2025 Office for Product Safety and Standards report identified a particular induction cooker presenting a serious fire risk because its plug fuse link did not conform to BS 1362 and was suspected to be counterfeit. That finding does not describe every portable hob.
Choose a traceable seller, inspect the supplied plug and cable, keep the product information and check current safety alerts for the specific appliance.

This portable induction hob is relevant if you have a compatible saucepan and want adjustable settings for cooking custard on a shared worktop. Check its cookware limits and controls against your routine before choosing it.

Consider this portable hob for custard if your saucepan suits induction cooking, and stay with the pan while it heats.
It will work only if its base is induction-compatible and meets the particular hob’s size requirements. CASO Design states that the ProSlim 2000 recognises induction pans with diameters of 12–22 cm; check your own pan and the instructions for the model you intend to buy.
Do not use an arrangement that overloads a socket or extension lead. Electrical Safety First warns against overloading them; follow the hob’s instructions, use a suitable wall socket where possible and stop using damaged leads or plugs.
Place it on a stable, heat-resistant worktop with the cable clear of water and hot surfaces, and stay with the pan to stir and monitor it. Keep flammable items away; Buckinghamshire Fire & Rescue Service advises turning off the heat if you need to leave the room.
Inspect the supplied plug and cable, keep the product information and check current safety alerts for the specific model. A 2025 Office for Product Safety and Standards report concerned one induction cooker with a non-conforming, suspected counterfeit plug fuse link; it should not be taken as a finding about other models.
