WIW: Waffled Sweet Potato Gnocchi

1 large baking potato (such as russet) and 1 large sweet potato (about 1½ lb. total)

1¼ C. all-purpose flour, plus more for flouring the work surface

½ C. grated Parmesan cheese

1 tsp. salt

½ tsp. freshly ground black pepper

Dash of grated nutmeg (optional)

1 large egg, beaten

Nonstick cooking spray or melted buter

Pesto or Waffled Sage and Butter Sauce

 

Preheat the oven to 350°F. Bake the potatoes until easily pierced with a fork, about an hour. Let the potatoes cool slightly, then peel them. (They may be just shy of the texture you’d want in a baked potato, but keep in mind they’re being cooked again later.) Pass the potatoes through a food mill or a ricer or grate them over the large holes of a box grater and into a large bowl. Add the 1 1⁄4 C. flour to the potatoes and use your hands to mix them together, breaking up any lumps of potato along the way. Sprinkle the cheese, salt, pepper, and nutmeg over the dough and knead lightly to distribute evenly. Once the flour and potatoes are combined, make a well in the center of the bowl and add the beaten egg. Using your fingers, work the egg through the dough until it starts to come together. It will be slightly sticky. On a lightly floured surface, gently knead the dough a few times to bring it together. It should be moist, but not wet and sticky. If it’s too sticky, add 1 T. flour at a time, up to 1⁄ 4 C.. Roll the dough into a log and cut it into 4 pieces. Roll each piece into a rope about the diameter of your thumb and then use a sharp knife to cut into 1-inch segments. Preheat the waffle iron on medium. Coat both sides of the waffle iron grid with nonstick spray, or butter the grids using a silicone pastry brush. Turn down the oven to its lowest setting and set aside a baking sheet to keep the finished gnocchi warm. Gently shake off any residual flour from the gnocchi and place a batch on the waffle iron, leaving a bit of space for each to expand. Close the lid and cook until the grid marks on the gnocchi are golden brown, 2 minutes. Repeat with the remaining gnocchi, keeping the cooked gnocchi warm on the baking sheet in the oven. Serve hot with Pesto Sauce or Waffled Sage and Butter Sauce. Variation: There’s another method possible: shaping the gnocchi in the waffle iron and boiling them. Follow the recipe through Step 6. Do not turn on the waffle iron. Dust the gnocchi lightly with flour, place them in the waffle iron, leaving space for the gnocchi to spread a bit, and close the lid. After 10 seconds, lift the lid, remove the gnocchi, and set them aside on a plate. Repeat until you’ve shaped all the gnocchi. At this point, the gnocchi can be boiled until they float, about 2 minutes, or flash-frozen in a single layer on a baking sheet for an hour, and then transferred to a zip-top bag for storage in the freezer. Frozen gnocchi will take an extra minute to cook.

 

Waffled Sage and Butter Sauce

 

Preheat waffle iron. Melt ½ stick salted butter and dip 16 large sage leaves into butter, then transfer them to the waffle iron. Cook until crispy and slightly browned, about a minute. Pour butter over gnocchi and garnish with sage.
