Ketumbar is the Indonesian word for "Coriander seed". In Malaysia Coriander seed is also called Ketumbar. Ketumbar (Coriandrum sativum) is an annual herb in the family Apiaceae. Ketumbar more popularly known as Cilantro, particularly in the United States. Serbuk Ketumbar refers to "Coriander Powder" . Come to think of it, I really do not know if we use Ketumbar in cooking Filipino foods and if we have Ketumbar in the Philippines. I think I heard already of the word "Katumbal" which refers to Siling Labuyo or hot chili peppers.
