Gomboce or knedle sa šljivama are plum-filled dumplings consumed throughout the Balkans, especially in Serbia and Croatia. The dough is made with potatoes, eggs, and flour. The potatoes should be cooked in their own skin, peeled, then mashed before they are combined with other ingredients.

Once prepared, the dough is rolled and plums are placed in the middle of each square, which is then assembled into a dumpling. These dumplings are boiled, then rolled in a combination of breadcrumbs, sugar, and (optionally) butter for the best experience.
