Closely related to potato pancakes, the potato waffle has one advantage -- it reheats exceptionally well and therefore can be made in advance. Serve with your favorite brunch foods, such as soft-boiled eggs and poached asparagus.
Ingredients
-
2 medium (about 13 ounces) Yukon gold potatoes
-
1 ½ teaspoons coarse salt, plus more for saucepan
-
2 cups all-purpose flour
-
1 teaspoon sugar
-
1 teaspoon baking soda
-
1 ½ teaspoons baking powder
-
3 large eggs, separated
-
2 cups nonfat buttermilk
-
8 tablespoons (1 stick) unsalted butter, melted
Directions
-
Peel potatoes, and cut each into eighths. Place in a medium saucepan of cold salted water. Bring to a boil, and simmer until potatoes are very tender, about 8 minutes. Drain, and set aside in a bowl to cool. Mash into coarse pieces with a fork or pastry cutter.
-
Heat the waffle iron. In a large bowl, sift together all purpose flour, sugar, baking soda, baking powder, and salt. Set aside.
-
In a medium bowl, whisk together egg yolks, buttermilk, and butter. Pour into the dry ingredients, and stir briefly, until just combined. Stir in potatoes.
-
In another medium bowl, beat egg whites until stiff but not dry. Fold into the batter.
-
Ladle about 1/3 cup batter onto each section of the waffle grid; spread batter almost to the edges. Close lid; bake until no steam emerges from waffle iron, 5 to 6 minutes.
-
Transfer waffles to a baking sheet; place in an oven set to low heat, about 200 degrees, while using remaining batter. Serve warm.
