Dami is a type of kateh cooked with herbs or vegetables. It is similar to kateh except that the heat is reduced to low immediately after the rice starts to boil. The lid of the pot is then wrapped with a dish towel (dam-koni) to prevent steam from escaping. After 40 minutes, remove the cover, pour oil or butter on top of the rice, re-cover, and continue cooking for another 20 minutes.
