A patanisca (isca in Porto) is a typical Portuguese dish. It is usually made by frying shredded bacalhau (patanisca de bacalhau) in a wheat flour, onion and egg purée, condimented with salt, parsley or pepper. Today, different recipes also include other types of fish (such as tuna), seafood or vegetarian alternatives.[1][2]
Pataniscas are approximately 8–12 cm (3.1–4.7 in) in diameter, but their shape is irregular and may be flat or spherical.[1]
