Fried Mashed Potato Cakes

In a large bowl, combine cold mashed potatoes, scallions, cheese and egg.

Add 3 Tablespoons of flour. If mixture needs additional flour, add up to 3 more, one tablespoonful at a time until potatoes come together.

Form potato mixture into pancakes about ¼ inch thick.

Place remaining ½ cup of flour on a plate and dredge both sides of the pancakes in the flour.

Meanwhile, heat vegetable oil in a skillet over medium high heat.

Carefully add pancakes and fry in batches until gold brown on both sides, about 3-4 minutes on each side.

Add additional oil if needed between batches.

Season with salt and pepper as soon as they are removed from the frying pan.

Serve with sour cream.
