Directions

1. Heat a large skillet of water and vinegar to a simmer over medium-high heat. Meanwhile, thinly slice the green onions. Set half aside for garnish.
2. In a bowl, combine the remaining green onions with the mashed potatoes, Cheddar, garlic, 1 egg, and flour. Season with salt (in moderation) and pepper. Mix until well combined. Form into four ½-inch-thick patties.
3. In a large skillet, melt the butter over medium heat until foaming. Cook the cakes for 3 min. per side, until golden brown. Transfer to a plate.
4. Meanwhile, gently crack the remaining 4 eggs, one at a time, into the simmering water and cook for 3 min., until whites are set, gently stirring to keep whites from spreading. With a slotted spoon, remove each egg from the water, blot on paper towels, and place on potato cakes. Garnish with reserved green onions.
