Bitterballen : These little meatballs are often served as part of a bittergarnituur, a selection of savoury snacks – bite-sized Gouda cheese, tiny egg rolls, sliced local sausage – to accompany drinks. Bitterballen are made from a mixture of chopped beef (or chicken, veal or mushrooms for a veggie option), which is cooked in broth, flour, butter and herbs. After chilling the mixture to firm it, it’s then rolled into small balls, coated with breadcrumbs and deep fried until crisp and golden. They are delicious dipped in grainy or spiced mustard and a firm favourite of Dutch top foods..
