Peka or sać is an ancient technique of preparing various dishes inside the eponymous bell-shaped cooking vessel. The technique is mostly used for the preparation of meat, vegetables, or seafood that are seasoned and cooked together with olive oil, other types of fat, herbs, and occasionally wine.
The dome-shaped lid is put on top, and the whole vessel is then placed in an outdoor fireplace, while the lid is covered with hot embers. This preparation technique allows the ingredients to cook slowly and keeps all the flavors and aromas intact.
Nowadays, peka is one of the signature techniques in Dalmatia, used to create hallmark dishes of the region such as veal (teletina) or lamb (janjetina) under the lid (peka), as well as octopus or bread baked under the lid. Apart from Dalmatia, the technique is also used in Istria and Bosnia, while it is also occasionally found in continental Croatia, Serbia, and other Balkan regions.
