Potato Pancakes (Placki kartoflane)

My mother made piles of potato pancakes when I was a kid.  She served them hot or room temperature.  The exact recipe remains a mystery because she didn’t follow a written recipe.  She simply threw everything together and made, the relatives all seemed to agree on this, the best “placki kartoflane” to be had.  The recipe below is based on her oral instructions.

8 medium potatoes
2 large eggs
12 tablespoons flour
2 medium onions
1/2 teaspoon salt
Canola oil
Butter

Grate the onions (or puree them in a machine) and add to a large mixing bowl with the salt and two eggs.  Mix well.  Grate the potatoes.  Add the potatoes and the flour to the bowl and mix well.

Place 2 tablespoons of oil and 2 or 3 pats of butter in a cast iron skillet.  Heat on high.  Add four dollops of the potato mixture and flatten.  When brown, flip and cook for about 4 or 5 minutes.  Remove to a hot plate and keep in a warming oven.  Add more oil and butter and make the next four pancakes.  Continue until all the mixture is used.  Serve immediately.

Poles usually serve potato pancakes with sour cream and/or apple sauce.
