Uncover ramekins; gently blot any condensation on custards with paper towel. Sprinkle 2 teaspoons sugar over each 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 Kitchen Tip). Place 2 tablespoons raspberries over each custard. Serve immediately, or refrigerate up to 8 hours before serving.
