Kotleti (Kotleta) are meat patties prepared with ground beef, veal, pork, chicken, or fish. The ground meat is mixed with minced onions and bread crumbs or crushed crackers and seasoned with salt and pepper. However, there are many variations of the recipe. Some recipes call for adding solid butter to make the patties even more tender, while other recipes suggest adding slices of white sandwich bread dipped into milk or cream.
