Ciorbă de peşte is a type of traditional Romanian sour soup made with vegetables, rice, fresh fish, and borş. The fish, 3 or 4 types (either sea bass, bream, halibut, carp, crucian, catfish, gray mullet, or luce), is boiled with a handful of rice and vegetables such as onions, carrots, potatoes, and a thick slice of celery root.
