I found the original recipe here. The only change I made to the recipe was I used half dark corn syrup and half light corn syrup. Otherwise, I followed the recipe exactly. I made two full batches of popcorn in my Whirley Pop popper and that was the perfect amount of popcorn.
Be sure to use a large enough pan to accommodate all the popcorn to make stirring easier. I used my turkey roasting pan.
If you want to be really decadent, melt some dark chococate and drizzle it over the top of the finished Caramel Corn - oh my!
