Those are not scoops of vanilla ice cream flanking onions (another Serbian favorite), but rather balls of kajmak (ky-mak) that you can read about if you click on the "right here" link above. Also pictured are a pair of Serbian homemade sausages with serving of smoked pork and a grilled pepper, tomato, and garlic salad. And the warm, crusty bread.... Leskovac is known for its spicy cuisine, and you can see that instead of ground black pepper beside the salt and toothpicks on the table are red pepper flakes...
