Choose a portable induction hob only after checking that your polenta pot has a magnetic, flat base within the model’s stated pan-size range. A domestic single-zone hob can suit a saucepan batch where worktop space is limited; a larger countertop unit is worth considering if your pot needs a wider supported base, provided you have space for the unit and a suitable electrical supply. Either way, adjustable heat and regular stirring matter as polenta thickens, while make-ahead portions also need a plan for cooling and reheating.
Start with the flat base of the pot you intend to use, then look for a hob whose published induction-pan range covers it. Tefal UK Shop and Buffalo Appliances publish different supported ranges for their respective models, so the pot matters more than the size of its rim.
A portable domestic hob may be easier to place and store between batches. Check its dimensions alongside its manual heat settings: you still need room to stand at the pot and stir as the polenta thickens.
Make room for portion containers and chilled storage before cooking. GOV.UK’s food-hygiene guidance addresses cooling and reheating for food businesses; at home, prompt chilling and thorough reheating remain practical parts of the make-ahead plan.
Match the pot to the hob before comparing controls or countertop size. A wider supported pan range helps only if the pot itself is induction-compatible and the unit fits where you will use it.
Consider it when: Your magnetic saucepan base fits the model’s published range and you want an extra zone that can be stored between uses.
Trade-off: A broad batch pot may exceed that range. Tefal UK Shop, for instance, specifies a 12cm–25cm base for the IH201840.
Consider it when: Your batch pot needs a wider supported base; Buffalo Appliances specifies 120mm–320mm for the CP799.
Trade-off: The CP799 has a 390mm × 490mm footprint and weighs 7.25kg. Check worktop space, ventilation clearance and the required electrical supply.
| Concern | What to check | Who this matters to |
|---|---|---|
| Pot fit and batch size | Check that the pot has a flat, magnetic base and measure its base against the exact hob’s supported pan range, not the pot’s rim. | If I cook a large batch in one pot, I need to know that the hob will accept the pot I already use. Roughly 36% of consumers put pot fit and batch size first. |
| Heat control | Compare manual power settings and the lower end of the stated range; do not treat a temperature setting as a measurement of the food. | As polenta thickens, I need to turn down the heat while I keep stirring. For roughly 29% of consumers, control during cooking is the primary concern. |
| Worktop and storage space | Measure where the hob will stand and be stored; check the model’s dimensions and required ventilation clearance. | If the hob is an occasional extra zone, I need to be able to put it away without giving up too much counter space. Compactness comes first for roughly 21% of consumers. |
| Saving portions safely | Prepare portion containers and fridge space, and plan prompt cooling, chilled storage and thorough reheating. | When I make polenta for later meals, I need a workable plan for the cooked portions, not just the cooking time. Around 14% of consumers make food handling their main priority. |
A pot can sit on an induction hob yet fail to heat if its base is not magnetic. A base outside the model’s stated pan range may also be unsuitable.
Test the base for magnetism, measure its flat contact area and compare that measurement with the exact hob model.
If your existing pot is unsuitable, you will need access to a compatible pot to use the induction hob.
The maximum rating does not tell you whether the hob accepts your pot or how you will reduce heat as the mixture thickens.
Compare pot-base compatibility, manual settings and footprint together. Consider a second zone only if you will cook something alongside the polenta.
A general soup or stew programme does not remove the need to watch and stir a thickening batch.
Use adjustable heat, stay with the pot and turn the setting down as needed while stirring.
The hob cannot provide the containers or chilled space needed after cooking.
Get those ready before starting. Cool and chill portions promptly and reheat them thoroughly; if preparing food for a business, follow the applicable GOV.UK food-hygiene requirements.

For an extra portable cooking zone when your polenta pot is induction-compatible and fits the hob.
The stated features include ten power settings, six functions, touch controls, a glass panel and a safety lock.
Before buying, confirm the supported pan-base range, lowest power setting and unit dimensions against your pot, cooking needs and available space.
It will need a magnetic base within that hob’s stated supported size range. Judge Cookware’s JEA90 manual requires magnetic cookware and a base of at least 12cm; other models have their own limits. Check the flat base rather than the rim, and test for magnetism if the pot is not clearly marked as induction-compatible.
A 2000W-class domestic hob can be an option for a saucepan batch if the pot fits and you can adjust the heat as the polenta thickens. Do not choose by wattage alone: Tefal UK Shop specifies a 12cm–25cm pot-base range for the IH201840, while Buffalo Appliances specifies 120mm–320mm for the larger CP799.
Clear manual heat adjustment matters more than relying on a named preset, because you need to respond as the mixture thickens. Compare the stated settings and lower power range, then stir and reduce heat as needed; a temperature setting does not guarantee the temperature of food in every pan.
Plan to cool and chill the portions promptly, then reheat them thoroughly before serving. GOV.UK’s food-hygiene guidance for businesses says food being hot-held must stay at or above 63°C and reheated food should be steaming hot throughout and reheated only once. Those business requirements should not be read as a statement of household-specific legal duties.
