Induction Hot Plate: Which Cookware?

Induction cooktops are becoming increasingly popular, and for good reason. They're safer, more energy-efficient, and more precise than traditional gas or electric cooktops. But what type of pots and pans can you use on an induction cooktop?

To work on an induction cooktop, the cookware must be made of a magnetic material, such as cast iron, carbon steel, or magnetic stainless steel. The cooktop uses electromagnetic fields to generate heat directly in the cookware, so only certain materials will work. You can test if your cookware is compatible by seeing if a magnet sticks to the bottom. If it does, it's induction-ready!

It's important to note that not all stainless steel cookware is compatible with induction cooktops. If the stainless steel has a high nickel content, it may block the magnetic field and not work with the cooktop. Additionally, aluminium, copper, glass, and non-magnetic stainless steel cookware will not work on an induction cooktop unless they have a magnetic disk attached to the bottom.

Cast iron, carbon steel, and stainless steel pans work on induction cooktops

Induction cooktops are becoming increasingly popular, and for good reason. They're safer, more energy-efficient, and more precise than conventional gas or electric cooktops. However, not all pots and pans are compatible with induction cooktops.

Induction cooking relies on the creation of a magnetic field between the pot and the magnetic coils beneath the cooking surface. This electromagnetic field generates heat in the pot itself, rather than the surface of the cooktop. Therefore, for a pot or pan to be compatible with an induction cooktop, it must contain ferromagnetic materials, such as iron or steel.

Cast iron, carbon steel, and stainless steel pans usually work on induction cooktops. These materials are ferromagnetic and can generate the necessary heat when placed on an induction hob.

When purchasing cookware for an induction cooktop, look for items specifically designed for induction cooking. These pots and pans will have a symbol indicating induction compatibility on the retail box or the bottom of the cookware.

Additionally, you can perform a simple test to check if your current cookware is compatible. Simply hold a magnet to the bottom of the pot or pan. If the magnet sticks, it means the cookware contains ferromagnetic materials and will work on an induction cooktop.

It is important to note that not all stainless steel cookware is compatible. Some stainless steel pans may have a high nickel content, which can block the magnetic field and prevent the cookware from working on an induction hob.

While cast iron, carbon steel, and compatible stainless steel pans are ideal for induction cooking, there are some types of cookware that should be avoided. Pots and pans made solely of glass, clay, copper, or non-magnetic stainless steel will not work on induction cooktops. However, some manufacturers offer cookware with a magnetized base specifically designed for induction, providing more options for consumers.

Non-compatible pans can be used with a metal disk

Induction cooktops are designed to work with pots and pans made of ferromagnetic materials, such as cast iron or certain types of stainless steel. This is because induction cooking involves creating a magnetic field between the pot and the magnetic coils beneath the cooking surface, which then heats the contents of the pot.

However, if you have a non-compatible favourite piece of cookware, you can still use it on an induction hob by placing a metal disk, such as a stainless steel induction hob heat diffuser, on the cooktop under the pan. The heating reaction will then heat the contents of the pan.

It is important to note that using a metal disk will be less efficient than using a ferrous cooking vessel. This is because the magnetic field cannot produce a concentrated current in non-ferrous metals, resulting in poor efficiency and possible damage to the cooktop.

Additionally, when using a metal disk, it is crucial to use a pan with a flat base that connects to the induction hob's cooking zone. An uneven bottom can cause vibration and noise on the glass surface, and it won't heat uniformly.

Therefore, while non-compatible pans can be used with a metal disk on an induction hob, it is recommended to invest in induction-compatible cookware for the best results.

Cookware must be flat-bottomed

For optimal performance, the cookware used on an induction hob must have a flat base. An uneven bottom can cause the cookware to vibrate and make noise on the glass surface, and it won't heat uniformly. The flat base should connect to the induction hob's cooking zone.

The size of the pan's base should match the induction cooking zone. Using a pan with a smaller bottom diameter than the hob creates a weaker magnetic field and less heat output.

The best lids for cooking on an induction hob are heavy enough to resist vibration when hot and to stay put if the food inside is bubbling hot.

Cookware with a magnetic bottom is compatible

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

To determine whether your cookware is compatible with an induction cooktop, you can perform the "magnet test". Simply hold a magnet to the bottom of the cookware. If the magnet clings to the underside, the cookware will work on an induction cooktop. If the magnet grabs the pan softly, you may not have much success with it on your cooktop. If there is no pull on the magnet, it doesn't contain the right metals and will not generate heat.

Cast iron, carbon steel, enameled cast iron, and many types of stainless steel cookware are all induction compatible. However, it is important to note that stainless steel can be confusing because it can be made with a variety of metals, and a high nickel content will block the magnetic field. Additionally, while aluminium, all-copper, or glass cookware will not work on their own, many manufacturers have started adding a magnetic layer to the bottom of these pans, making them compatible with induction cooktops.

When shopping for cookware to use on an induction cooktop, look for products that are labelled "induction-ready" or "induction compatible". You can also look for the induction-compatible symbol, which often looks like a horizontal zig-zag or a coil.

Pots and pans with a non-stick coating can be used

For pots and pans to work on an induction hob, they must be made of a ferromagnetic material, such as cast iron or some stainless steel. This is because induction cooktops use direct electrical induction heating, creating a magnetic field that induces an electrical current in the cooking vessel. The iron in the pot then concentrates the current to produce heat in the metal.

Non-stick pans can be used on induction hobs, provided they have a magnetized base. The interiors of these pans are typically made of heavy-gauge die-cast aluminium with a magnetized base, allowing for the rapid heat transfer of an induction stove. The non-stick coating can be derived from stone, hard-anodized, or other types of coatings.

When shopping for non-stick pans to use on an induction hob, it is important to look for pans that are cadmium and lead-free, and contain no APEO, PFOA, NMP, and NEP (lesser-used chemicals). Additionally, ensure that the base of the pan is flat and connects to the induction hob's cooking zone. An uneven base can cause the pan to vibrate and make noise on the glass surface, and it won't heat uniformly.

It is also worth noting that not all stainless steel pans are compatible with induction hobs. Some stainless steel pans with too much nickel content may react magnetically but may not work on an induction hob. Therefore, when shopping for induction cookware, look for "induction-ready cookware" or "induction cooktop cookware."
