1 can sweetened condensed milk
1 cup Karo syrup
1 stick butter
2 cups brown sugar
cook on stove over medium heat stirring frequently. cook to soft ball stage. Pour over popcorn that has been separated from kernals. Mom used a really big silver bowl, or her insert to her turkey roaster. I like my popcorn balls a little gooier, so the amount of popcorn is really up to you. You might just make a few batches to determine how much you like.
Once you stir the carmel and the popcorn up you use a little bit of cold water on your hands so you can manipulate the popcorn into balls with out burning your hands, but not so much that you make your popcorn balls soggy.
