Kartoffelsalat Mit Biermarinade (Pot. Salad/Beer Dress.)

Kartoffelsalat mit Biermarinade is a German potato salad dressed in a warm beer sauce instead of the usual vinegar or mayonnaise. Melted butter and flour cook into a roux, then dry mustard, sugar, beer, and hot sauce get whisked in and brought to a boil. The result is a thick, tangy, slightly yeasty dressing that clings to every slice of warm potato.

The potatoes soak in the warm beer dressing for a full hour before the bacon, onion, and celery go in. That rest is where the flavor develops. Warm potatoes are porous and absorb dressing like a sponge, so by the time the hour is up, every slice is seasoned all the way through.

Crispy bacon pieces, chopped onion, and celery get tossed in at the very end to preserve their crunch. Adding them with the dressing would soften the bacon and wilt the celery.

Kitchen Tips

• Boil the potatoes whole and peel them while still warm. Hot potatoes peel easily and absorb the dressing better than cold ones.
• Slice the potatoes about ¼ inch thick for the right balance of structure and absorbency. Too thin and they break apart. Too thick and the dressing stays on the surface.
• Stir the roux constantly when adding the beer. It foams up and can lump if you pour too fast.
• Serve at room temperature. This salad is best warm, not hot, and not refrigerator-cold.

Variations

• Use a dark lager or wheat beer for a deeper, maltier dressing.
• Add a tablespoon of grainy mustard for more texture and sharpness.
• Toss in diced dill pickles for a tangy crunch alongside the bacon.
