How Does Induction Cooking Work?

The act of cooking is a culmination of skill set and the ability to apply heat to raw food and turn it into something eatable.

Once you have these ingredients, you can prepare any food no matter how complicated.

In most homes today, there are only a few devices people use, mainly hob based heating. They are:


1. Use the proper oil

By igniting a combustible material such as coal, charcoal, gas or wood, you can produce flame which produces heat. This heat is then transferred by the surrounding air to a cooking pot to prepare food. This method is used decades past and is fast fading from the modern cooking scene.

Choosing the right oil for your deep fryer is half battle won. Once you know the type of oil you want to use, you will need to fill up the fryer with it, taking care not to over-fill or under-fill it.

If you have a model that have a minimum or maximum fill line, it becomes even easier as you have a ready gauge to guide your measurement.


2. Turn it on and start operating

You can generate heat by apply electrical current to a resistance element. This method is often used in toasters and electric copper coils. When the heat is produced, the flame generated is transported directly to food or the cooking vessel to cook food. This can still be found in most homes albeit they are fast approaching their tipping point.

To start using your device, you need to turn it on by plugging it in and using the switch button to power it up.

After that, set the temperature and time and ensure that you obtain the right level of temperature for the oil without going over that.

You also need to maintain a temperature between 350 degrees F and 375 degrees F which is the suitable range for most of the cooking you will be doing.

If your device comes with a thermostat, you don't have to bother too much about the temperature as it will automatically determine the correct temperature.

However, if it doesn't come with one, you may have to get yourself a thermometer to select the right temperature for the oil.

Induction Cooking

3. Pat your food dry

This is relatively more modern and quite different from the above models. It uses a electromagnetic technology that has been in existence since the 90s. By electro-magnetically exciting tiny molecules contained in compatible metals in induction pans, the cookware generates heat (so that there is no transfer of heat) that cooks food item.

Three components are needed for this method to work:

  • check
    A cooking pan/pot made of stainless steel
  • check
    A coil of copper wire mounted under a glass ceramic cooktop
  • check
    Electrical supply
Before drying any kind of food, make sure it is dried and doesn't have any traces of water. You can make use of a kitchen paper towel or cover the food in some dusting to remove any traces of water.

For example, freshly cut potatoes can be wiped with paper towel so that there is no water on it before throwing them into the fryer. Not doing this may cause some dangerous spilling of oil that may be injurious to you or children around.

How it Works

4. Lower the food slowly into the fryer

An electrical supply is first applied to a copper coil which generates a high frequency electromagnetic field that interacts with the magnetic-based cooking pan or pot through the glass ceramic cooktop.

The components from the cooking pot is separated from the copper coils by the ceramic glass cooktop, which is a very poor conductor of heat such that the cooktop becomes immediately cook to the touch when the cooking pot is separated from the hob.

Then the process reaches a molecule level where eddy currents are generated in the ferrous metal contained in the cooking pot. The eddy current produces the heat that is then transferred to the contents in the pot since they are in direct contact. Only the content that is connected to the to the cooking pot is affected by the heat and nothing outside of its contact is touched.

The heating process halts immediately the pot is removed from the cooktop or when it’s switched up.

As you can see, this process is not only faster but safer than the other two methods of heating mentioned above. The reason why most people have not adopted this kind of cooking method is that of budget because they are costly. 

Some fryers come with a basket that you can place the food you want to fry and carefully lower it into the fryer and once it's lowered it should lock in place.

However some models don't have this luxury and you may have to use a slotted spoon or your hands to get the food into the fryer. Whichever one you go with, you need to ensure you do it slowly to avoid any hazard.

Hey, I'm Cath :) Iv'e got two beautiful young girls who mean the world to me. I used to be a head chef over at my local restaurant but I gave that up to look after my girls. I decided to put my culinary experience to use here by bringing that wealth of kitchen related knowledge and sharing it with you guys.
