pan on a rack. While it is cooling, follow these instructions to make the first frosting: Mix about 1.5 cups sugar, about one third cup butter and about half cup of half-and-half in a heavy, medium-size saucepan. Bring to a boil, then cook over moderate heat without stirring until a small amount of the mixture forms a soft ball when dropped in ice water, or it reaches 110ºC . on a candy thermometer. Remove from heat immediately and cool in a pan of ice-water until the candy is lukewarm. DANGER: melted sugar cools very slowly. You can burn yourself badly by testing it with your finger. Add about 1 teaspoon vanilla extract to the candy. Beat it until it is creamy and of a spreading consistency. This is most easily done with an electric mixer, although you can use a heavy wire whip. Spread the frosting over the brownies. Melt the remaining 3 oz chocolate and spread over the frosting just put on the brownies. Cover as evenly as possible. Cool for several hours in a refrigerator, then bring to room temperature and cut into pieces to serve. Be very careful when melting chocolate. It burns easily. A double boiler is probably the best way thing to use. It is critical to cook the first frosting to just the right point. If cooked too little, it will be too thin to beat to a creamy consistency. If cooked too much, it will be too brittle. So keep a close eye on it; sugar tends to cook slowly to the soft-ball stage, then it cooks quickly.
