In a large bowl, combine the mashed potatoes, cheddar cheese, scallions, egg, and 3 tablespoons of flour. Mix until fully combined.

Divide the mixture into 12 portions using your hands. Roll each portion into a compact ball and flatten it into a pancake about 1/2 inch thick.

Place the remaining 1/2 cup of flour in a shallow dish. Dredge each pancake in the flour, coating thoroughly.

Heat 3 to 4 tablespoons of vegetable oil in a large sauté pan over medium heat, ensuring the bottom of the pan is thoroughly coated with oil.

Cook the pancakes in batches, frying until golden brown and crispy on both sides, about 3 to 4 minutes per side. Do not overcrowd the pan and avoid flipping the pancakes too soon.

Transfer the pancakes to a paper towel-lined plate and sprinkle them with salt immediately. Serve with sour cream and additional chopped scallions as garnish.
