How To Clean Cast Iron Kadai?

  1. Clean The Kadai

    First, rinse the Kadai and add a few drops of diluted dishwashing liquid in the Kadai.

  2. Scour The Kadai

    Using a soft brush/scrub, scourge the Kadai thoroughly. Ensure that you clean the outside as well. Do not use excessive force or steel wool as it could damage the seasoning.

  3. Rinse The Kadai

    After thoroughly scouring the Kadai, rinse it thoroughly. Ensure there is no soap residue left on the surface.

  4. Dry The Kadai

    Keep the Kadai on the stove and heat it on a low flame to completely dry the Kadai. We do not recommend using a towel to dry the Kadai because water drops would be left on the surface.

  5. Apply oil

    Using an oil dispenser, apply a thin layer of oil. An oil dispenser with brush helps apply oil evenly without smearing on your hands. Then, using a clean towel, remove any excess oil on the surface. This step is important as excess oil will cause incomplete polymerization and a sticky surface.

  6. Start The Seasoning Process.

    Heat the Kadai on a high flame till oil starts smoking. You may have to carefully move the Kadai around holding it using a thick towel to ensure that the sides too get heated and smokes.

  7. Cool And Store

    Once the oil is all smoked out, switch off the stove and allow it to cool. Store it in a dry place away from moisture. Rinse the Kadai before use next time.

Which oil is best for seasoning?

In the US, they recommend Canola ( Rapeseed) oil for seasoning. However, it is not commonly available in India. The basic premise is that the oil should have high-fat content and low smoking point so that you can get a nice layer of seasoning. So, we recommend using Sunflower or Gingelly oil. Avoid using coconut oil as it could develop a rancid smell.

Which is better? Seasoning on stovetop or oven?

Both methods are equally effective. However, we prefer to do it on the stovetop as you can see when the oil dries up and if needed apply another coat of oil so that the cookware develops a thick layer of seasoning.

Why does my cast iron pan get sticky?

Sometimes cast iron surface gets sticky after seasoning because the oil has not polymerised completely. Reheat the pan so that the oil starts smoking. This helps to remove the stickiness and develop proper seasoning on the pan’s surface. To prevent cast iron pan from getting sticky, dab away the excess oil on the surface before you heat the cookware.
