Currywurstsoße

Currywurstsoße belongs to the Berlin Imbiss, the snack stand, more than to any church feast. Its season is the late shift, the football match, the weeknight when a pan of sauce makes a cheap sausage worth sitting down for. This is city food, postwar food, budget food, and it still deserves a proper pot. Das ist kein Bierzelt.

Berlin wants it bright, tomato-red, and spooned over sliced skinless Brühwurst, the scalded sausage. The Ruhrgebiet puts it over a grilled Bratwurst and often likes the sauce darker and sweeter. Hamburg keeps its own origin argument. Im Norden anders, im Süden anders, and in the west louder than both. I won't settle the claim. I will make the sauce so it tastes cooked, not squeezed.

The technique is simple and it matters: cook the tomato paste and curry powder in fat before the liquid goes in. Do that, and the paste loses its raw tin edge while the curry wakes up in the oil. Pour in the tomato too early and you can simmer all evening and still get dusty spice and flat ketchup. Brick-red paste, orange oil, then liquid. Erst verstehen, dann kochen.

The thrift is the old lesson in a modern coat: onion, canned tomato, apple, vinegar, a spoon of Rübenkraut, and a small tin of spice. The apple gives fruit and body, so you don't need bottled ketchup. The vinegar and salt wait until the sauce has reduced, because a sauce lies before it has cooked down. Watch the spoon. When it coats and drops slowly, it is ready for sausage, Pommes, and one last yellow dusting.
