Makes 6 patties
Cook the potato and turnip in a large pot of boiling water for 15 to 17 minutes or until tender. Drain the vegetables and transfer to a bowl. Mash with either a fork or potato masher and then stir in green onions, egg, flour and salt and pepper to taste.
Coat the bottom of a heavy bottom skillet with about ¼ of oil and heat over medium high heat until the surface of the oil begins to shimmer. Using a ¼ cup measurer, spoon the mixture into the oil and flatten with a spatula into patties. Cook for about 2-4 minutes on each side, or until golden brown, and then transfer to a plate lined with paper towels to drain the excess oil.
Serve with sour cream if desired. Yum!
