• FAST

Ingredients

1. 10 fingerling potatoes, scrubbed and halved lengthwise
2. 1 tablespoon extra-virgin olive oil
3. Salt and freshly ground pepper
4. 2 tablespoons pressed caviar (2 ounces)
5. 1/2 cup sour cream

1. Preheat the oven to 400°. On a large rimmed baking sheet, toss the potatoes with the oil; season with salt and pepper. Arrange the potatoes cut-side down and bake for about 25 minutes, until tender and browned on the bottom. Let cool to warm.
2. Meanwhile, roll out the caviar between 2 sheets of plastic wrap to a 5-by-6-inch rectangle about 1/8 inch thick. Cut the sheet into 20 diamonds or rectangles.
3. Transfer the potatoes to a platter cut sides up and dollop sour cream on each. Top with the caviar diamonds and garnish with the chives. Serve right away.
