Things you need to know about Persian Cuisine

Over time, four methods have developed for preparing Persian rice: kateh, damy, chelow, and polo. Kateh is simply rice steamed with water, salt, oil or butter, and sometimes saffron. Damy is rice steamed more slowly and mixed with uncooked ingredients, like beans or grains. Chelow is parboiled rice mixed with seasonings and/or herbs, then slowly steamed to form a crispy tahdig (sometimes spelled tahdeeg).
