A gas hob is excellent for producing instant heat and for responding immediately to a change of setting: heat produced on a gas hob can be reduced as quickly as it can be increased. The flame is always visible on a gas hob so it's very easy to adjust the gas hob to the exact heat that you require. This immediacy makes the gas hob the number one choice for professional cooks.
A gas hob doesn't require natural gas provision. Bottled gas (LPG) works just as well, and the gas hob heats and responds in exactly the same way as with mains gas. LPG may not be as clean as natural gas, but for anyone with limited funds, buying a cylinder of propane gas every few months for your gas hob is a good way to help with the family budget.
There are three types of
electric hob. Most are now smooth and
ceramic so when the milk boils over, it is unable to collect under the rings. While you do have to clean up an overspill pretty quickly, spills are much easier to wipe up than they used to be. The three main types of electric hob are:
The solid plateThis type of electric hob has been around for years. However, it's still popular and is available as a built-in worktop unit or a portable freestanding unit.
The radiant spiralThis is also a longstanding favourite. A relic of the 1950s electric cooker but now the radiant coils of the cooker are usually concealed beneath a ceramic hob, rendering this cooker easy to clean.
Halogen hobsThis type of heating is the newest of the three. It's quick and clean, incorporating a halogen light under a ceramic plate. Halogen hobs are the ultimate flat hotplate, with a ceramic glass top which glows when it’s switched on. Halogen hobs are slightly safer than the other two hob types as you are less likely to put a plate, a cloth or - heaven forbid - your hand on a glowing red element.
Induction hobs are the most 'magical' of hob types, and have been around since the 1970s. It is also one of the safest hobs on the market. This is because induction hobs don't begin to heat up until a saucepan or metal casserole is placed upon them. This means that there are no knobs, and hence no danger of forgetting to turn the cooker off.
When a
saucepan is placed on the induction hob, a magnetic circuit is created. When the saucepan is removed from the hob, the circuit is broken and the power is cut. An induction hob only works with cooking pots that have a magnetic field. This means that copper, aluminium and heatproof glass are unsuitable for induction hob cooking.
There is now an even more pioneering type of induction hob which is promoted as being 'zoneless'. This is a great innovation as any size of magnetic container can be placed anywhere on the surface of the hob and sensors under the surface will 'read' the dimensions of the container and just heat that one covered area. This is ideal if you wish to heat up a griddle and a couple of saucepans of different sizes. Induction hobs of this kind put pay to moving things around like pieces on a chessboard.
