Grab a big bowl and toss in mashed potatoes, scallions, shredded cheddar, beaten egg, and 3 tablespoons of flour. Stir until it's combined well.

Using your hands, split the mixture into a dozen equal parts. Press each into a compact ball, then flatten them into round patties around 1/2 inch thick.
03 -
Pour the reserved flour (1/2 cup) into a shallow dish. Roll each pancake in the flour until it's nicely coated all over.
04 -
Add 3-4 tablespoons of vegetable oil to a sauté pan. Heat it over medium and make sure the oil spreads evenly at the bottom.
05 -
Carefully lay the patties in the pan, cooking them in small batches. Let them crisp up until golden, about 3-4 minutes per side. Don’t crowd the pan or flip too early.

Move the cooked pancakes onto a plate lined with paper towels and sprinkle them with salt straight away. Add a dollop of sour cream and a few scallion pieces on top for garnish.
