Introduction
Cooking with a Kadhai is a popular tradition in many kitchens, as it can perform a variety of purposes starting from whipping up deep-fried delicacies to savory stir-fries.
As times have evolved, the materials and coatings that are used in these versatile cooking vessels have also changed.
Modern induction Kadai are made up of non-stick coatings.
The non-stick coating makes cooking and cleanup much easier.
What is a non-stick coating?
Non-stick coatings are a different kind of surface that prevents other materials from sticking to the surface.
This makes cooking hassle-free and cleaning much easier.
The most common material that is used for non-stick coatings is polytetrafluoroethylene (PTFE).
Basic of PTFE
PTFE is a type of synthetic polymer that is made up of carbon and fluorine atoms.
It is done through a chemical process called polymerization.
In this process, the small molecules are combined to form a large, chain-like molecule.
PTFE is especially important for its non-reactive ability and low friction properties, which makes it an ideal non-stick surface.
How does non-stick Coating work?
The working of PTFE is mainly based on its molecular structure.
The strong bonds between carbon and fluorine form a unique kind of slippery surface that prevents sticking.
When this material is applied to a Kadhai, this coating allows the food to be cooked evenly without sticking to the pan, with the use of minimal oil.
This is easy and convenient and also contributes to healthier cooking by reducing the need for excessive fats.
Applying Non-stick coating to Kadhai
The process of applying a non-stick coating to a Kadhai involves a variety of steps. The surface of the Kadhai is cleaned properly to remove any substances. The cleaning ensures that the non-stick coating works properly.
Then a primer layer is applied to the Kadhai for elevating the magic of the non-stick coating.
The non-stick material is sprayed or rolled onto the surface. This is done in many layers to increase its longevity.
Lastly, the Kadhai is heated to high temperatures to cure the coating.
Benefits of Non-stick Kadhai
A non-stick Kadhai makes cooking easier and smoother. Foods like eggs, pancakes, and delicate fish fillets can be cooked very effortlessly on the surface. Cleaning the kadhai is very easy and convenient.
With just a simple wipe with a sponge, all the leftover food can be removed and washed away.
Non-stick coated Kadhai requires less oil. This minimal oil requirement of the Kadhai contributes to a healthier diet. Foods can retain their natural flavors and nutrients without the need for excess oil.
With proper care and maintenance, non-stick Kadhai can last for a long time. PTFE is safe under normal cooking conditions, but it is advisable to avoid high heating the non-stick Kadhai.
Extremely high temperatures can cause the coating to break down and release harmful substances.
Conclusion
The secret of non-stick coatings in modern Kadhai consists of a combination of chemistry and practical benefits that elevate the cooking experience.
Understanding the function and importance of PTFE and the way it can be applied to cookware, helps to appreciate the technology that makes our lives easier.
