Coat the bottom of a large non-stick pan with the oil. Place the pan over medium-high heat. Using a tablespoon or ice cream scoop, place a spoonful of the batter in the skillet. Flatten out the tops of the fritters as they cook. Repeat using all the batter, refreshing the oil as needed in between each batch. Cook each fritter until it is golden brown, about 2-3 minutes per side. Serve the fritters immediately or keep warm in a low oven until ready to eat. Garnish with chopped scallions and serve with yogurt of sour cream.
