Bitterballen are a popular Dutch snack, typically served in bars and at parties. They are small, round balls filled with a rich, savory mixture of beef or veal ragout, which is then breaded and deep-fried until golden brown. This makes them crispy on the outside and soft on the inside. Often enjoyed with a side of mustard for dipping, Bitterballen are a favorite among locals and tourists alike. They are commonly served as part of a larger platter of Dutch snacks, making them a staple in Dutch cuisine and a must-try for anyone visiting the Netherlands.
