I've made these a few times & they are very close to the ones my Mother & GranMother used to make.
Emeril's Potato Pancakes
2 1/2 pounds baking potatoes, peeled
1 medium onion, julienned
2 eggs
1/4 teaspoon baking powder
2 tablespoons all-purpose flour
Salt
Freshly ground white pepper
Vegetable oil, for frying
Using a hand grater or food processor, grate the potatoes. Wring dry in a dish towel. Put into a mixing bowl, and toss with onion, eggs, baking powder, and flour. Mix well. Season with salt and pepper.
In a large skillet, over medium-high heat, cover the bottom with 1/2-inch of oil. When the oil is hot, spoon 2 tablespoons of the filling into individual cakes. Using the back of the spoon, flatten each pancake. Pan-fry until golden brown on each side, about 2 to 3 minutes. Remove from the oil and drain on paper towels. Fry the cakes in batches and do not over crowd the pan.
