How to Make It
In a large saucepan, cover the potatoes with cold water. Bring to a boil and cook until the potatoes are almost tender, about 8 minutes. Drain and let stand until cool enough to handle. Cut the potatoes in half lengthwise.
Meanwhile, in a small bowl, whisk the sour cream with the yogurt, dill, chives, onion and caraway and season with salt and pepper.
In a large cast-iron skillet, heat the olive oil until shimmering. Cook the potatoes in two batches cut side down until golden brown and tender, about 10 minutes. Transfer the potatoes to a platter and season with salt and pepper. Drizzle the potatoes with the dill sauce and serve.
Smoked or poached salmon.
