Preheat oven to 300 F.
In a medium saucepan, mix together the apple juice concentrate, butter
and Karo. Stir in pecans. On medium heat, continue to stir until the
pecans are coated and little liquid remains.
Spread in a lightly buttered cookie sheet, separating pecans as much as
possible. Bake 10 minutes; remove from oven and spread pecans on
aluminum foil, separating nuts to cool.
