Lamb or beef (precisely 20% fat, 80% meat) is minced twice for finer consistency. A mixture of lamb and beef is also
popular. Salt, black pepper, very finely grated onion and optionally one egg yolk per pound of meat is added. All
ingredients are mixed, covered, and left to marinate in the refrigerator for at least one hour or overnight.
Kabab koobideh is grilled on wide, flat skewers, traditionally over hot coals, and is served with chelow (plain white
rice with oil, salt and saffron), accompanied by grilled tomatoes and onions. Sumac is usually served as a tableside
garnishing spice.
