1 1/2 cups granulated sugar
3/4 cup firmly packed brown sugar
1/2 cup butter
1/2 cup milk
2 tbsp corn syrup

Stir together first 5 ingredients in a heavy 3-quart saucepan. Bring to a boil over medium heat, stirring constantly. Boil, stirring constantly, 7 to 8 minutes or until a candy thermometer registers 234F.
Remove from heat, and vigorously stir in pecans. Spoon pecan mixture onto wax paper, spreading in an even layer. Let stand 20 minutes or until firm. Break praline-coated pecans apart into pieces.
