After proper seasoning of a cast iron wok (using the seasoning a cast iron wok with salt method) the first time you heat the wok up again for your first wok recipe in the newly seasoned wok (after seasoning a cast iron wok for the first time or re-seasoning a cast iron wok using the seasoning a wok with salt method heat the wok as normal and add a small amount of oil before cooking - as always for wok cooking) you will be amazed at how smooth and slick the surface is with foods literally gliding over it.
