Waterzooi or "Viszooitje" is a Belgian dish of stew, originating in Flanders. The second part of the name derives from the Middle Dutch terms "sode", "zo(o)de" and "soot", words referring to the act of boiling or that what is being boiled. It is sometimes called Gentse Waterzooi which refers to the Belgian town of Ghent where it originated. The original dish is often made of fish, either freshwater or sea, (known as Viszooitje), though today chicken waterzooi (Kippenwaterzooi) is more common. The most accepted theory is that rivers around Ghent became too polluted and the fish there disappeared. It is said to have been the favourite dish of Charles V, Holy Roman Emperor who was born in Ghent. Bycatch is the reason this dish exists, so there is not really a specific recipe.
