""Pommes frites"" or just ""frites"" (French), ""frieten"" (a word used in Flanders and the southern provinces of the Netherlands) or ""patat"" (used in the north and central parts of the Netherlands) became the national snack and a substantial part of several national dishes, such as Moules-frites or Steak-frites. Fries are very popular in Belgium, where they are known as "frieten" (in Dutch) or "frites" (in French), and the Netherlands, where among the working classes they are known as "patat" in the north and, in the south, "friet(en)". In Belgium, fries are sold in shops called "friteries" (French), "frietkot"/"frituur" (Belgian Dutch), "snackbar" (Dutch in The Netherlands) or "Fritüre"/"Frittüre" (German). They are served with a large variety of Belgian sauces and eaten either on their own or with other snacks. Traditionally fries are served in a "cornet de frites" (French), "patatzak" /"frietzak"/"fritzak" (Dutch/Flemish), or "Frittentüte" (German), a white cardboard cone, then wrapped in paper, with a spoonful of sauce (often mayonnaise) on top.
