Ingredients

1. 1 pound all-purpose potatoes, peeled and cut into 2-inch chunks
2. 1/4 cup self-rising flour
3. 3 large eggs
4. 1/3 cup heavy cream
5. 1/3 cup milk
6. 1 teaspoon kosher salt
7. Pinch of freshly ground white pepper
8. 2 large egg whites
9. 2 tablespoons canola oil

Directions

1. Cook the potatoes in boiling salted water until tender, about 15 minutes. Drain, then press through a large fine strainer into a bowl. Let cool slightly, then beat in the flour and eggs.
2. In a small saucepan, bring the cream and milk to a simmer. Add to the potatoes and whisk until smooth. Season with the salt and white pepper. Beat the egg whites until firm, then fold them into the potato batter.
3. Heat 1/2 tablespoon of the oil in a large nonstick skillet. Spoon 3 tablespoons of the batter into the skillet for each pancake and cook over moderate heat until golden on the bottom and barely dry on top, about 2 minutes. Flip the pancakes and cook until golden, about 2 minutes longer. Add some more of the oil for each batch. Serve hot.

Make Ahead

The pancakes can be refrigerated overnight. Rewarm, slightly overlapping, on a baking sheet in a 325° oven for about 20 minutes.
