1 cup leftover mashed potatoes
1 cup all-purpose flour
2 tsp baking powder
2 tsp salt
2 eggs, lightly beaten
1/4 cup (about) milk to mix
Butter or oil for frying
Sugar (optional)
Place the grated raw potatoes in a clean cloth and twist to remove excess moisture. Whisk together flour, salt, and baking powder. Combine flour mixture into raw potatoes, mashed potatoes, and eggs. Add enough mix to make a batter. Heat a heavy skillet over medium heat and add butter or oil. Drop potato batter by the tablespoon into the hot pan. Brown on both sides (about 4 minutes per side). Butter each boxty and serve hot with or without sugar.
