Uncover ramekins; gently blot any liquid from tops of custards with paper towel. Sprinkle 2 teaspoons granulated sugar over each chilled custard. Holding kitchen torch 3 to 4 inches from custard, caramelize sugar on each custard by heating with torch about 2 minutes, moving flame continuously over sugar in circular motion, until sugar is melted and light golden brown. (To caramelize sugar in the broiler, see Broiler Directions below.) Serve immediately, or refrigerate up to 8 hours before serving.
