Grain & Rice Techniques
Rice Techniques: Ab-Kesh & Dam Kardan
Also: ab-kesh, dam kardan, آبکش, دم کردن, Persian parboil-and-steam, chelo method
The two-stage Persian rice method — a full parboil-and-drain (ab-kesh) followed by a cloth-wrapped steam (dam kardan) — that produces supremely fluffy, separate grains and an ideal base for tahdig.
/ab-KESH (آبکش) | dam kar-DAN (دم کردن)/Both terms are Persian. Ab (آب) = water; kesh (کش) = pull/drain. Dam (دم) = breath, steam; kardan (کردن) = to do/give. The method has been codified in Persian culinary tradition for at least several centuries and is foundational to the Safavid-era courtly rice culture.
Definition
Ab-kesh and dam kardan are the paired techniques at the core of Persian chelo (plain steamed rice) and polo (rice with mix-ins), forming together the most nuanced long-grain rice method in world cooking. Ab-kesh (literally 'water pull') refers to the parboiling stage: well-rinsed, often pre-soaked long-grain basmati is cooked in heavily salted boiling water — as salty as pasta water — for five to eight minutes, until the grains have elongated and the exterior is cooked but the very center remains chalky. The rice is then immediately drained (ab-kesh, pulling the water off), sometimes briefly rinsed with cool water to halt cooking and wash away surface starch. This stage is non-negotiable: the parboil softens the grain, elongates it, and removes excess starch so that individual grains will never clump in the final steam. Dam kardan (literally 'giving breath' or 'allowing the breath') is the steaming stage. The drained rice is returned to the pot over fat (on top of the tahdig base), mounded in a loose pyramid, then covered with a pot lid wrapped tightly in a clean cotton or linen cloth — called the dam cloth or dami. The cloth absorbs the condensation that would otherwise drip back onto the rice and make it sticky. Steam builds inside the sealed pot, the cloth-captured heat rises through the mound, and the rice cooks through over low heat for 45 to 60 minutes. The result is grains that have lengthened to nearly twice their dry length, fully cooked yet distinct and non-sticky, with a feather-light texture. Together, ab-kesh and dam kardan achieve what no absorption method (the standard in most of the world) can: grains that never touch each other, a complete absence of glue-starch gumminess, and the controlled environment for a flawless tahdig below.
In use
“After the ab-kesh, the rice will look slightly underdone — that is correct; the dam kardan will finish it gently over the next hour.”

Notes
Soaking before ab-kesh
Many Persian cooks soak basmati for 30 minutes to several hours before boiling. Soaking hydrates the center of the grain, allowing a shorter, more controlled parboil — reducing the risk of the outside overcooking before the core softens. It also accelerates the grain's elongation in boiling water.
The dam cloth
The cloth wrapped around the lid is not decorative. Steam condensing on a bare metal lid would drip back as large water droplets, making the top layer of rice gummy. The cotton cloth absorbs this condensation, ensuring the steam inside the pot remains dry. A thick cloth also provides gentle insulation, moderating temperature swings. Specialized metal dami lids with raised domes exist, but most cooks favor a cloth-wrapped standard lid.
Kateh: the shortcut
Kateh is the Gilani (northern Iranian) absorption method — rice cooked all the way in its own water without draining, more like a standard pilaf. It produces a softer, stickier rice and a thinner tahdig but requires far less attention. In Gilan it is considered everyday rice; the two-stage ab-kesh/dam method is the formal, laborious ideal.
