Bitterballen is a popular Dutch meat snack that is commonly found in Amsterdam. These small, deep-fried meatballs are typically filled with a mixture of beef or veal ragout, seasoned with herbs and spices. Bitterballen are crispy on the outside and soft and creamy on the inside. They are often served with mustard for dipping and are a perfect accompaniment to a cold beer at a local pub or bar.
