This is awesome caramel corn! I doubled the recipe and used 3 cups of white sugar and 1 cup of brown sugar. I don't like Cracker Jacks b/c it tastes burnt to me. This recipe (using the sugars combo I used) tastes just like caramel, a bit more flavor than toffee. Next time I won't double the recipe b/c it makes it too hard to stir the caramel into the corn to get it all even. I stirred the corn every 20 minutes. I also added the peanuts to the syrup mixture before pouring over the corn. If I don't do it that way the peanuts just fall to the bottom of the bowl/bag. Much better adding them to the syrup.The syrup took 5 minutes for me, so be sure to test at 5 minutes. I tested mine the old-fashioned way, using ice water and droping some syrup into the ice water to see if it reached the hard boil stage (300 degrees). I also air popped my corn. Thanks so much for posting. I love this recipe. I lost my favorite years ago and have used a lot of recipes since that were too bitter. This is perfect!
