Walnut Caramels

1. Line an 8x8x2- or 9x9x2-inch baking pan with foil, extending foil over edges of pan. Butter the foil. If desired, sprinkle walnuts onto bottom of pan. Set pan aside.

2. In a heavy 3-quart saucepan melt butter over low heat. Add brown sugar, half-and-half or cream, and corn syrup; mix well. Cook and stir over medium-high heat till mixture boils. Clip a candy thermometer to the side of the pan. Reduce heat to medium; continue boiling at a moderate, steady rate, stirring frequently, till the thermometer registers 248 degree F, firm-ball stage (45 to 60 minutes).

3. Remove saucepan from heat; remove thermometer. Stir in vanilla. Quickly pour the mixture into the prepared pan. When caramel mixture is firm, use foil to lift it out of pan. Use a buttered knife to cut into 1-inch squares. Wrap each piece in plastic wrap. Makes about 2 pounds (64 pieces).
