Janjetina ispod peke is a traditional lamb specialty that calls for preparing the meat under a metal, bell-like dome or lid called peka in Dalmatia or čripnja in Istria. The meat is usually combined with potatoes and vegetables such as onions, tomatoes, carrots, and zucchinis, and the whole thing is then commonly drizzled with olive oil.

White wine or beer may occasionally be added to the concoction to speed up the cooking process, while the dish is often flavored with aromatic herbs and spices such as rosemary, bay leaves, mint, paprika, and black pepper. Traditionally, the baking tray or pot containing the food is topped with the peka lid, placed in a fireplace, and the lid is then covered with hot embers on top.

After hours of cooking slowly under the lid, the meat comes out tender, succulent, and falling-off-the-bone. This specialty is typically accompanied by a fresh seasonal salad, kruh ispod peke (bread baked under the lid), and a glass of white wine or beer on the side.

Janjetina ispod peke is a typical dish of the Dalmatia and Istria regions, where it can be savored in local restaurants or prepared at home.
