Why this recipe works: Amish potato salad is distinct for its egg-enriched, creamy cooked dressing and the sweet-and-sour flavor that comes from vinegar and sugar. We modernized this traditional recipe by ditching the traditional cooked-egg dressing. To keep the rich taste with less work, we processed a hard-cooked egg yolk in the dressing to mimic some of the heft of the cooked dressing. Sour cream added body, tang, and richness to the sweet-and-sour dressing, making up for the missing butter and oil. We set aside a few teaspoons of the dressing before adding the sour cream, and drizzled it over the hot cooked, cubed potatoes. This helped the potatoes soak up more of the rich flavor.

pounds Yukon Gold potatoes, peeled and cut into ¾-inch chunks
Salt and pepper
cup cider vinegar (see note)
tablespoons yellow mustard
large hard-cooked eggs, peeled
teaspoon celery seed (see note)
cup sour cream
celery rib, chopped fine
1. COOK POTATOES Bring potatoes, 1 tablespoon salt, and enough water to cover by 1 inch to boil in large pot over high heat. Reduce heat to medium and simmer until potatoes are just tender, about 10 minutes. 2. PREPARE DRESSING While potatoes simmer, microwave vinegar and sugar in small bowl until sugar dissolves, about 30 seconds. Process vinegar mixture, mustard, 1 hard-cooked egg yolk (reserve white), celery seed, and ½ teaspoon salt in food processor until smooth. Transfer to medium bowl. 3. SEASON POTATOES Drain potatoes thoroughly, then transfer to large bowl. Drizzle 2 tablespoons dressing over hot potatoes and, using rubber spatula, gently toss until evenly coated. Refrigerate until cooled, at least 30 minutes, stirring gently once to redistribute dressing. 4. ASSEMBLE Whisk sour cream into remaining dressing. Add remaining hard-cooked eggs and egg white to dressing and, using potato masher, mash until only small pieces remain. Add dressing and celery to cooled potatoes. Cover and refrigerate until chilled, about 30 -minutes. Season with salt and pepper. Serve. (Salad can be refrigerated in airtight container for 2 days.) Cook's Notes: 1. We processed a hard-cooked egg yolk into the dressing to mimic the flavor and some of the heft of the cooked dressing while reducing the work. 2. We whisked in sour cream for body, tang, and richness. It made up for the butter (or oil) that was in the original cooked dressing.
