In Azerbaijan, kükü (read: kyukyu) is the general name given to dishes in which main ingredients—vegetables, herbs, meat or fish—are bound with eggs, then browned on both sides on a stovetop. It is not to be confused with omelet, as the featured ingredients in kükü are used in far greater amounts than eggs. By its appearance and texture, kükü can be likened to a Persian kookoo, Middle Eastern eggah, Spanish tortilla or Italian frittata.
Simplicity in itself, fresh herb kükü is by far the most popular and the most frequently made kükü of all in the versatile kükü repertoir. In this light summer dish, fresh herbs are mixed with eggs, then the mixture is leveled in a frying pan and cooked in butter on both sides to yield a tender, flavorful interior laced with a golden surface.
