2 cups sugar
1 ¾ cups dark Karo syrup
½ lb. butter (no substitutes)
1 pint whipping cream
1 tsp vanilla
1 cup walnuts
Cook sugar, Karo, butter and ½ cup cream until mixture reaches a rolling boil.
Add remainder of cream slowly and cook to a stiff ball or 243 degrees on candy thermometer. (NOTE: For Utah and higher elevations, adjust temp to 235 degrees)
Remove from heat and add nuts and vanilla.
Pour into buttered 9 X 13 X 2" pan and let cool overnight.
Cut into squares and wrap in waxed paper. Absolutely the best caramel EVER!
You can also cook to 240 degrees; roll out on waxed paper, put marshmallows in center and roll into a log.
Let set and slice and wrap in waxed paper.
