Kabab-e donbalan is a traditional offal dish originating from Iran. This type of kebab is usually made with a combination of lamb testicles, lemon juice, olive oil, salt, and pepper. The testicles are cut lengthwise, then mixed with olive oil, lemon juice, salt, and pepper.
Once marinated, the testicles are threaded on skewers and grilled on both sides over hot coals. During the cooking process, they are basted with the marinade a few times. Once done, fresh lemon juice and sumac are sprinkled over the testicles, and kabab-e donbalan is served hot with bread and pickled vegetables on the side.
