Induction Pans: Identifying The Right Cookware For Your Stovetop

Induction cookers are becoming an increasingly popular alternative to conventional gas or electric cookers. Induction cookers work by creating a magnetic field between the pot and the magnetic coils beneath the cooking surface, which means that only certain types of pans will work. To know if a pan is compatible with an induction cooker, you can perform what is known as the 'magnet test'—simply place a magnet on the base of the pan, and if it sticks firmly, it will work with your induction cooker. If it doesn't stick, the pan does not have the metals required to create heat with an induction cooker. Another way to check is to look for an induction compatible symbol on the bottom of the pan, which looks like a coil of wire, or for the word induction to be inscribed on it.

The magnet test: a magnet will stick to induction pans

Induction cooktops work by creating a magnetic field between the pot and the magnetic coils beneath the cooking surface. This means that for a pan to be compatible with an induction cooktop, it must contain ferromagnetic materials, such as iron, or have a layer with magnetic properties.

The magnet test is a simple way to determine whether your pan is induction-compatible. Simply grab a magnet—such as a refrigerator magnet—and place it on the base of your pan. If the magnet sticks firmly, your pan will work with an induction cooker. If the magnet does not stick, your pan does not have the metals required to create heat with an induction cooker.

It is important to note that if the magnet only sticks softly, the pan may still work with your induction cooktop, but it may not work efficiently. The magnet needs to adhere to the pan very well. If it slides off easily, the pan may not have enough magnetic qualities to work effectively with an induction stove.

The magnet test is a quick and easy way to determine whether your pans are induction-compatible. However, it is not the only test. Another way to check is to look for the induction-ready symbol, which is often a horizontal zig-zag or coil, stamped on the bottom of the pan or printed on the exterior packaging.

The boiling water test: induction pans will not give an error message

Induction cooktops are very different from conventional gas or electric cooktops, and only certain types of pans are compatible with them. Induction cooking uses electromagnetism to produce heat, which directly heats up the cookware while keeping the cooktop surface cool. This method has several benefits, such as being more energy-efficient, heating food faster, and being safer due to the cool cooktop surface.

To determine whether your cookware is induction-ready, you can perform the boiling water test. This test involves pouring a small amount of water into the pot or pan you wish to test and placing it on the induction cooktop. If the cookware is induction-friendly, it will heat up and boil the water. However, if the cookware is not induction-compatible, the cooktop may display an error message or start beeping. This is because induction stoves only work with cookware made of ferrous metals, such as cast iron, stainless steel, or enameled cast iron, which are magnetically compatible.

The boiling water test is a simple and effective way to check if your cookware is induction-ready. If the cooktop displays an error message or starts beeping, it indicates that the cookware is not compatible with induction cooking. In this case, it is best to use cookware specifically designed for induction cooktops to ensure optimal performance and avoid any potential issues.

It is important to note that while using non-induction compatible cookware on an induction cooktop will not damage the stove, it is still a safe practice to avoid doing so. This is because repeatedly placing non-induction cookware on the stovetop may cause the hob to overheat and malfunction. Additionally, some pans made from materials like aluminum or copper with a magnetic base can be used on induction cooktops, but they are not ferrous metals. This may cause the induction hob to constantly work at full power, leading to potential issues such as overheating or warping pans.

To summarize, the boiling water test is a helpful way to determine if your cookware is induction-ready. If the cooktop displays an error message, it indicates that the cookware is not compatible with induction cooking. In this case, it is advisable to use cookware specifically designed for induction stoves to ensure a safe and efficient cooking experience.

The induction logo: check for a coil or zig-zag symbol

The induction logo is a quick and easy way to check if your pan is suitable for an induction hob. The logo usually takes the form of a coil or zig-zag symbol, often accompanied by the word "induction". This symbol can be found on the bottom of the pan or printed on the exterior packaging. If you see this symbol, your pan is definitely induction-compatible.

However, the absence of the induction logo doesn't necessarily mean that your pan isn't compatible. Some manufacturers may not have labelled their induction-compatible pans, so you can perform a simple magnet test to double-check. Simply hold a magnet to the bottom of the pan. If it sticks firmly, your pan will work on an induction hob. If it doesn't stick at all, your pan is not compatible. If the magnet only sticks softly, the pan may work but not efficiently.

It's worth noting that some materials, like stainless steel with high nickel content, may react to magnets but still not work on an induction hob. This is because induction hobs require ferromagnetic materials, such as cast iron, carbon steel, or stainless steel.

Pan material: iron or iron-based pans are induction-compatible

Induction cookers use magnetic fields to generate heat, so the best pans for induction stovetops are those made from ferrous metals, i.e. metals that contain iron. Cast iron pans are therefore ideal for induction cooking. Cast iron is a great retainer of heat and, as it's a fantastic conductor, it works very well with induction cookers. The iron in the pan draws in the electromagnetic current, which means the pan itself becomes the source of energy.

Cast iron pans are heavy-duty, hardy, and durable, but they are not sleek, and they are not smooth. Cast iron pans often have rough bumps or scratches on them, which can cause scratching on a glass induction cooktop. It is possible to smooth down the bottom of a cast iron pan with an iron file, but this is time-consuming. An alternative is to use enameled cast iron pans, which are lighter, smoother, and more modern. Enameled cast iron is just as conductive as standard cast iron, but the enamel coating can slow down the heating process.

To check whether a pan is induction-compatible, you can perform the magnet test. Simply place a magnet on the base of the pan, and if it sticks firmly, the pan will work with your induction cooker. If the magnet doesn't stick, the pan doesn't contain the right metals to create heat on an induction cooker.

Pan base: a flat, thick base is best for induction

The base of a pan is the most important part as it transfers the heat to the food. The thickness of the base varies depending on the material and price. A thick base is generally better and has several advantages. Firstly, a thick base is more resistant to denting and warping. Secondly, it provides even heating and searing qualities. However, a thick base will take longer to heat up.

When choosing a pan for an induction cooktop, it is important to ensure that the base is flat. A flat base will ensure that the pan sits evenly on the cooktop and maximizes the heat conduction. A wobbly pan with a curved base will not only be unstable but also cause the oil to run to the edges. Therefore, when selecting a pan for induction cooking, look for one with a flat, thick base. This will provide you with even heating and prevent warping.
