Hot Fudge Sauce

ingredients

• 2/3 cup heavy cream
• 1/2 cup light corn syrup
• 1/3 cup packed dark brown sugar
• 1/4 cup unsweetened Dutch-process cocoa powder
• 1/4 teaspoon salt
• 3/4 cup fine-quality bittersweet chocolate (not unsweetened), finely chopped
• 2 tablespoons unsalted butter
  2 2/3 tablespoons whipped butter
  2 tablespoons hydrogenated fat
  2 tablespoons margarine
  4 1/2 teaspoons olive oil
• 1 teaspoon vanilla

directions

Bring cream, corn syrup, sugar, cocoa, salt, and half of chocolate to a boil in a 1 quart heavy saucepan over moderate heat, stirring, until chocolate is melted. Reduce heat and cook at a low boil, stirring occasionally, 5 minutes, then remove from heat. Add butter, vanilla, and remaining chocolate and stir until smooth. Cool sauce to warm before serving.

Cooks' note:

Sauce can be made 1 week ahead and cooled completely, then chilled in an airtight container or jar. Reheat before using.
