  2. Step 2: Wash the vessel on day 5 and fill it with rice washed starch water. Repeat this process for 4 days. Throw the water every morning and fill it with fresh rice washed starch water.

          Arrowroot powder / rice / maida powder can be used as an alternate.

  1. Step 3: On day 9, fill the vessel with rice washed starch water and heat it in the stove in low flame. Switch off the gas once the water boils. Repeat this process for 4 days.

Caution in using Kalchatti

  • Do not do seasoning / tadka directly in the vessel in the initial days of cooking, for around 15-20 uses. Post this, direct seasoning / tadka/ or onion frying can be done.
  • For the first 15-20 uses always make sure the vessel has liquid in it before placing on the stove and cooking is done only in low or medium flame and not in high flame.

We received a seasoned Kalchatti.  Should we still season it?

You should pour starch water, boil in low flame and repeat the process for 3 days before cooking. This helps the vessel to get used to the heat of your stove.
