1 c. butter
1 16 oz. pkg. (2 1/4 c. packed) brown sugar
1 c. light corn syrup
1 14 oz. can sweetened condensed milk
1 tsp. vanilla

Generously butter a 9 x 9 x 2 inch pan; set aside. In a heavy 3 quart saucepan melt the butter. Add sugar and dash salt; stir thoroughly. Stir in corn syrup. Gradually add condensed milk; stir constantly. Cook over medium heat, stirring occasionally, to 245°F (firm-ball stage), for 15 to 20 minutes (mixture should boil gently over entire surface). Remove from heat; stir in vanilla. Pour into buttered pan. When cool, cut into squares with a wet, sharp knife. Wrap each piece in clear plastic wrap.
