Cauliflower Gnocchi

Step 1

Make the gnocchi: Heat oven to 450 degrees. Wrap cauliflower and potato separately in aluminum foil. Roast on a baking sheet until tender, 1 hour. Unwrap and let cool slightly. Cut cauliflower into 4 equal pieces and transfer to a large bowl. Halve potato lengthwise and scoop out flesh into bowl; discard skin.

Step 2

Press roasted cauliflower and potato through a ricer onto a clean work surface. Sprinkle 3/4 cup flour and the salt evenly on top and set the yolk on the vegetables. Using a bench scraper or long side of a metal spatula, cut into the mixture, folding over and blending in the flour and yolk into the riced cauliflower mixture, until well incorporated, dusting work surface with flour occasionally to prevent sticking. Gather mixture into a ball and gently knead a few times to form a soft dough. Cut into 2 equal pieces.

Step 3

Bring a large pot of water to a boil. Meanwhile, working with one piece of dough at a time, roll into a 3/4-inch-thick log that is about 24 inches long. Using a sharp knife, cut into 1-inch pieces and transfer gnocchi to a lightly floured baking sheet. Repeat with remaining dough.

Step 4

Add half the gnocchi to boiling water and cook until they start to float, then simmer just until puffed and cooked through, 1 1/2 to 2 minutes longer. (Do pay attention: If the gnocchi are boiled too long, they will start to disintegrate.) Using a spider or slotted spoon, transfer gnocchi to an oiled baking sheet and roll to generously coat in oil to prevent gnocchi from sticking to one another. Repeat with remaining gnocchi.

Step 5

In a large nonstick skillet, melt 4 tablespoons butter over medium heat. Add half the gnocchi and half the capers and season with salt and pepper. Cook, stirring occasionally, until gnocchi is golden and crispy, about 5 minutes. Stir in half of radishes and half of lemon juice (it may splatter). Divide in 2 shallow bowls and top with chives. Repeat with remaining butter, gnocchi, capers, radishes, lemon juice and chives.
