Cast iron cookware are seasoned using the traditional technique documented from various grand mothers. Having said that, we recommend one final step for the customers to do before first use: Wash the cookware really well, keep it in gas burner with two spoons of oil and fry an onion for 7-10 mins in medium flame. Discard the onions and the cookware is ready for use. Only reason we do not do this final step is because the cookware looks like an used one. After cooking, we recommend that after you wash the cookware, wipe it clean off water and apply some cooking oil and store them. This will help in protecting the seasoning and prevent it from rusting.
