- 1/4 cup olive oil
- 3 large russet (baking) potatoes (about 1 1/2 pounds total), scrubbed
- 1 tablespoon dried dill
- 9 ounces caviar such as salmon roe
- 8 ounces crème fraîche or sour cream
- Preheat oven to 375° F. and brush 3 large baking sheets generously with some oil.
- With a mandoline or other manual slicer cut 1 potato crosswise into 1/8-inch-thick slices. Immediately arrange slices in one layer on 1 baking sheet and brush with some remaining oil. Sprinkle potatoes with dill and salt and pepper to taste.
- Bake slices in middle of oven until golden, 15 to 20 minutes, and with a metal spatula immediately transfer to a rack to cool completely. Repeat procedure with remaining potatoes and baking sheets in same manner. Potato chips may be made 3 days ahead and kept in an airtight container at room temperature.
- Top potato chips with 1 teaspoon each of caviar and crème fraîche or sour cream, side by side.
