German Potato Salad with Dill

Cover 2 pounds halved small waxy potatoes with cold salted water, bring to a boil, and cook until tender; drain and transfer to a large bowl. Meanwhile, heat 1/4 cup olive oil in a medium skillet over medium-high heat. Add 1/2 chopped onion; season with salt and pepper. Cook, stirring often, until soft, about 5 minutes. Remove from heat and mix in 1/4 cup apple cider vinegar. Add to potatoes along with 4 sliced scallions, 2 tablespoons chopped fresh dill, and 1 teaspoon toasted caraway seeds and toss, crushing potatoes slightly; season with salt and pepper.
