I make it this way.
First squeeze excess liquid from grated potatoes using a kitchen towel. In a large
bowl combine potatoes, onions, flour, salt, egg and pepper. Heat oil in a nonstick
pan over medium heat. Spoon potato mixture into skillet, and cook until the edges
of pancakes are crisp and golden brown.
Here is a donut recipe too.
Oil
3 cups sugar
2 eggs plus 1 egg yolk
3½ cups unbleached flour
¼ cup cocoa
1 tablespoon baking powder
½ teaspoon salt
1 cup buttermilk
Combine ¼ cup oil, 1 cup sugar, eggs and egg yolk in bowl and beat with electric mixer until fluffy.
Sift together flour, cocoa, baking powder and salt. Stir into oil mixture alternately with buttermilk. Heat 2 to 3 inches oil in heavy deep skillet to 340 degrees. Drop batter by tablespoons into hot oil and cook in batches until doughnuts are evenly fried, 2 or 3 minutes per side. Do not crowd pan.
Drain on paper towels. Roll in remaining 2 cups sugar.
