Individual Caramel Flan

To caramelize sugar, in a heavy 8-inch skillet cook 1/3 cup sugar over medium-heat until sugar begins to melt, shaking the skillet occasionally to heat the sugar evenly. Do not stir. Once the sugar starts to melt, reduce heat to low. Cook about 5 minutes more or until all the sugar is melted and golden, stirring as needed with a wooden spoon. Immediately divide the caramelized sugar among 4 (6-oz.) custard cups; tilt custard cups to coat bottoms evenly. Let stand for 10 minutes.
