German Potato Salad
Prep: 20 minutes · Cook: 30 minutes · Total: About 50 minutes · 6 as a side
Ingredients
The potatoes
- 1 kg waxy potatoes (about 6 medium) — red-skinned, fingerling, or German Salad potatoes; russets disintegrate into paste here
- 1 tbsp (12 g) salt, for the boiling water
The dressing
- 8 slices bacon (about 150 g), cut crosswise into 1 cm lardons before cooking
- 1 medium onion (about 150 g), diced fine
- 45 ml (3 tbsp) apple cider vinegar
- 100 ml (about 7 tbsp) chicken or beef stock, warm
- 15 g (1 tbsp) sugar, plus more to taste — the sweet-sour balance is the dish
- 1 tsp (5 g) Dijon or whole-grain mustard
- 3/4 tsp (4 g) salt, plus more to taste
- Black pepper
- 10 g (1/4 cup) chopped fresh parsley or chives
Instructions
- Boil the potatoes whole and unpeeled, 25–30 minutes. Cover with cold salted water, bring to a gentle simmer, and cook until a knife meets just-past-resistance at the largest potato's center. Unpeeled boiling keeps the skins as jackets against waterlogging and makes the later peel a ten-second job. Checkpoint — the knife slides in with a soft give and meets no hard core; the skin has cracked in a line or two. Err one minute under rather than one over — the potato cooks again when it hits the warm dressing.
- Render the lardons and build the dressing in the fat, 10 minutes. Cook the lardons in a wide pan over medium heat until crisp at the edges but still giving — 8 minutes — then lift out half (they return at the end). Add the onion to the fat and cook 3 minutes until translucent, then add the vinegar, warm stock, sugar, mustard, salt, and pepper, and simmer 2 minutes, scraping the pan's bottom — the browned bacon and onion fond dissolves into the dressing, which is half its flavor. Checkpoint — the dressing is a glossy, loosely syrupy liquid that smells sweet-sour and smoky; a spoonful coats and slowly falls. It should taste slightly too sharp and too sweet at once — the potatoes absorb both extremes.
- Slice and drench while hot — the law. Peel the hot potatoes with a paring knife and fork (the jackets slip), slice into 5 mm coins, and drop them into the serving bowl in batches, spooning a ladle of dressing over each batch as it lands. Toss gently with a spatula — the slices are fragile — and let the bowl sit 5 minutes; the hot potatoes pull the dressing into their cut faces. Checkpoint — after the 5-minute rest, the bottom of the bowl is nearly dry — the potatoes have drunk the dressing. That dryness is the proof of the law. A pool of dressing means the potatoes cooled first; it will taste like potato soup instead of potato salad.
- Finish, decide the temperature, serve. Fold in the reserved lardons and the parsley, taste, and adjust — vinegar for tang, sugar for round, salt last. Serve warm in the German register, or let it come to room temperature over an hour, where it becomes a different, picnic-great salad. Checkpoint — eating test: the potato coin is tender and glossy through, dressed to its center, with sweet, then sour, then smoke in the swallow and a lardon's crunch arriving every third bite. It should taste nothing like the mayo bowl — this is potato candy with a backbone — and the #36 classic is the other country's answer.
Doneness & Quality Checkpoints
- Waxy potatoes boiled whole, one minute under
- Half the lardons held back for the finish
- Dressing simmered with the fond scraped in
- Potatoes sliced and drenched hot — the bowl drinks near-dry
- Sweet-sour tasted at the end, not assumed
Finish & Plate
A wide ceramic bowl, warm if serving warm — the parsley and reserved lardons across the top so the first spoonful carries them. Bratwurst or any grilled sausage is its oldest partner; it also stands beside fried chicken, an Octoberfest plate, or a Tuesday's eggs. In Bavaria it pairs with a wheat beer; the file seconds the region.
Troubleshooting
| Symptom | Cause | Fix |
|---|---|---|
| Salad gluey, pasty | Starchy potatoes or over-boiling | Waxy potatoes; pull one minute early |
| Dressing separated, greasy | Cold stock into hot fat | Warm stock; simmer the dressing to one gloss |
| Tastes sharp only, no roundness | Sugar short or vinegar heavy | Sugar in 5 g steps at the final taste |
Storage, Make-Ahead & Variations
- Keeps 2 days refrigerated (4 °C); serve cold, room temperature, or re-warmed with a splash of stock in a pan. Do not freeze — the thawed potato grain goes grainy and waterlogged. - Variations: the Swabian purist's (sugar halved, chives only); the version with a spoon of the potato's own boiling water in place of stock; the American sweet-hand; crispy fried onions on top for the county-fair register — and the #36 mayo classic stands as the northern border of this potato salad's map.
