Chocolate Turtles

2 C light cream
1 1/2 C white sugar
1/2 tsp salt
1/2 C brown sugar
1 C light corn syrup
1/3 C butter
1 tsp butter
Pecans
Melted Chocolate

In heavy saucepan, heat cream to lukewarm. Pour out 1 cup and reserve. To remaining cream in saucepan, add sugar, corn syrup and salt. Cook over moderate heat and stir until it boils. Very slowly stir in reserved cream (1 cup) so mixture does not stop boiling. Cook and stir constantly for 5 minutes. Stir in butter, about 1 tsp at a time. Turn heat down low. Boil gently and stir part time until temp. reaches 248 degrees, or until small amount dropped in cold water forms a firm ball that does not flatten when removed from water. Remove from heat. Gently stir in vanilla and cool slightly. Pour over pecans placed in a cake pan. When cold, cut in squares and dip in chocolate.
