Psarosoupa
Psarosoupa is the Greek word for a fish soup, traditional to Greek cuisine. There are several variations on the soup. All include fish and vegetables. The types of fish used vary: carp, cod, hake, mackerel, salmon, skate, trout, turbot, perch, haddock, and swordfish are all possibilities. Some prefer a firm, white-fleshed fish, such as grouper, snapper, or rockfish, and avoid more oily fish. Psarosoupa may be served with retsina.
