Toffee
From the Joy of Cooking
Heat the above ingredients and stir until mixed well. Stop stirring. Using a candy thermometer let the mixture heat up to 285 degrees F (without stirring). It will start carmelizing at about 270 degrees.
Mix in 1/2 cup nuts if desired.
I pour the toffee onto a cookie sheet covered with wax paper. Spread the toffee out to the desired thickness. Let cool.
Melt 6 ounces semi-sweet chocolate chips. Spread chocolate on top of toffee. Cover with 1/2 cup nuts and press nuts into chocolate. Let cool.
