• Make-Ahead

Ingredients

1. 1/4 cup salt-packed capers, rinsed
2. 1 1/2 pounds medium Yukon Gold potatoes
3. Salt
4. 1/4 cup extra-virgin olive oil
5. 1 tablespoon freshly squeezed lemon juice
6. Freshly ground pepper
7. 1/2 small red onion, thinly sliced
8. 3/4 pound smoked sablefish or salmon, thinly sliced
9. 2 tablespoons parsley leaves, for garnish
10. Lemon wedges, for serving

Directions

1. In a small bowl, cover the rinsed capers with warm water. Let stand at room temperature for 30 minutes. Drain.
2. Meanwhile, in a large saucepan, cover the potatoes with cold salted water and bring to a boil. Lower the heat and simmer until tender, about 30 minutes; drain. While the potatoes are still warm, peel and slice them 1/4-inch thick. Transfer the potatoes to a large bowl.
3. In a small bowl, combine the olive oil, lemon juice and capers and season with salt and pepper. Pour two-thirds of the dressing over the potatoes and toss.
4. Arrange the potatoes, onion and sablefish on a platter. Drizzle with the remaining dressing, garnish with the parsley and lemon wedges and serve.
