Different sources try to differentiate between buridda and burrida, stating that one or other is the famous Genoese fish soup served over large croûtes or a Sardinian dish of dog fish and skate topped with breadcrumbs, chopped nuts, garlic and nutmeg, or even a Ligurian dish of dried cod with tomatoes, mushrooms and anchovies. Since they generally disagree about which spelling belongs to which dish I think you must try to establish which is on offer by other means. In Liguria it is likely to be a soupy stew of fish with tomatoes, vegetables, pine kernels and including anchovy fillets, sometimes made with dried vegetables. In Sardinia, where it may also be called "la burrida", it could either be a dog fish soup or the dish described above.
