Pommes Rot-Weiss

Pommes Rot-Weiss is a creature of the German Imbiss — the kiosk-and-snack-stand culture that spread across the country in the postwar decades, above all in the industrial Ruhr region around Dortmund and Essen. 'Pommes' is short for Pommes frites, the French term for fried potatoes that German took up; the German chip is cut thicker than the French and fried golden and substantial. The rot-weiss order — ketchup and mayonnaise together — became the standard way to dress them, and the natural partner to Currywurst, the curried-sausage snack that Berlin's Herta Heuwer is credited with creating in 1949. To ask simply for 'Pommes rot-weiss' at a German Imbiss is to order without further explanation.

A heap of thick golden chips, crisp at the edges and fluffy inside, with a broad red ribbon of ketchup and a white ribbon of mayonnaise laid across the top. You eat them with a small wooden fork, dragging each chip through whichever sauce — the sweet-tangy ketchup or the rich, faintly sharp mayo — or both at once. Hot, salty, and unpretentious, best from a kiosk on a cold evening, ideally with a Currywurst alongside. The contrast of crisp potato and cool sauces is the whole appeal.

The chip itself is the technical part: thick-cut potatoes are traditionally fried twice. A first, lower-temperature fry around 150-160°C cooks the potato through and drives off surface moisture; a rest, then a second, hotter fry near 175-180°C crisps and browns the outside while the inside stays fluffy. Frying once at a single temperature gives either a pale soft chip or a burnt-outside-raw-inside one. The two sauces are added cold at the end and never cooked, their coolness and acidity playing against the hot, salted, starchy potato; the mayonnaise's fat also rounds out the leaner ketchup.
