Zwiebelsauce Mit Speck Zu Kartoffeln
"Es wird Speck in kleine Würfel geschnitten, langsam gelb gebraten und dabei oft umge= rührt; dann werden recht viele Zwiebeln, ebenfalls in kleine Würfel geschnitten, dazu gegeben, und, wenn auch diese gebräunt sind, 1—2 Eßlöffel Mehl eine Weile darin durchgerührt, Essig, Wasser und Salz nach Geschmack hinzugefügt und die Sauce gut durchgekocht Will man eine helle Zwiebelsauce, so läßt man das Mehl nur gelb werden und die Zwiebeln erst zuletzt in der Sauce weich dämpfen"
English Translation
"Bacon is cut into small cubes, slowly fried until golden while stirring often. Then quite a lot of onions, also cut into small cubes, are added, and when these are browned as well, 1–2 tablespoons of flour are stirred in for a while. Vinegar, water, and salt are added to taste, and the sauce is cooked thoroughly. If you want a light onion sauce, let the flour only turn yellow and then steam the onions in the sauce until soft at the end."
Note on the Original Text
The recipe reflects the concise, efficient style of 19th-century cookbook writing: ingredients and actions are woven together without formal lists or precise measurements. Quantities are 'nach Geschmack' (to taste), emphasizing intuition and experience in the kitchen. German spelling is mostly modern, though some ligatures and word divisions (e.g. 'umge= rührt') mirror old typesetting practices. The instructions rely on the cook's existing knowledge, assuming familiarity with methods such as making a roux (Mehl anschwitzen) or balancing flavors.

This recipe hails from Henriette Davidis, one of 19th-century Germany’s most important domestic authorities. Her practical cookbooks were a staple in German-speaking households, guiding everyone from beginner cooks to experienced housewives. The Zwiebelsauce mit Speck is a classic example of everyday, hearty fare designed to accompany simple dishes, particularly boiled potatoes. It captures the resourceful, flavor-forward cuisine of the time, where inexpensive ingredients like onions and bacon could be transformed into something deeply satisfying.

Preparations in the late 19th century would have used a sturdy iron or copper pan placed over a wood- or coal-fired stove. Onions and bacon would have been cut with a well-sharpened kitchen knife on a solid wooden board. Stirring would be done with a wooden spoon, ensuring nothing caught at the bottom of the pan. Measuring was typically done by eye or with household spoons rather than precise scales. Water would be ladled or poured from a jug, and vinegar kept in a stoneware bottle.

Ingredients
- 3.5oz smoked bacon (or substitute with unsmoked if necessary)
- 2 large onions (approx. 10.5oz), finely diced
- 0.5–1oz (1–2 tablespoons) all-purpose flour
- 0.5–1 fl oz (1–2 tablespoons) vinegar (apple cider or white wine vinegar)
- 7 fl oz water
- Salt, to taste
Instructions
- Cut 3.5oz of smoked bacon into small cubes.
- Place the bacon in a heavy-bottomed pan and gently cook over medium-low heat, stirring frequently, until the fat renders and the bacon turns golden yellow.
- While the bacon cooks, finely dice 2 large onions (approximately 10.5oz).
- Add the diced onions to the pan with the bacon and continue to cook, stirring often, until both the bacon and onions are well browned and soft.
- Sprinkle 1 to 2 tablespoons (0.5–1oz) of all-purpose flour over the mixture, stirring continuously to ensure the flour does not form lumps.
- Cook the flour for a few minutes until it just begins to take on a golden color.
- Add a splash (about 1–2 tablespoons or 0.5–1 fl oz) of vinegar, 7 fl oz of water, and salt to taste.
- Bring to a simmer and cook for several minutes, stirring frequently, until the sauce thickens and the flavors meld.
- For a lighter version of the sauce, cook the flour just until yellow but do not allow it or the onions to brown.
- Then add the onions last and steam them gently in the finished sauce until just soft.
