Bring karo, sugar, butter to boil; add whipping cream slowly; do not allow the boiling to stop; stir constantly. Boil to hard ball stage (242°F at sea level -- calibrate your candy thermometer!)
Add nuts and vanilla; do not beat. Pour into buttered pan
and when cool, cut into 1-inch squares and wrap each in wax paper and then in
colored Christmas paper to cheer them up.
Note: Definitely NOT diet delights!
