I haven't even seen the salt and vinegar kind.
I used to LOVE the ActII White Cheddar Cheese (microwave, you popped the corn and added ina flavor packed of white cheddar, YUMMMMM They don't make it around here anymore. They make kettle corn, which is good, but you don't get to add anything
At the local festivals there is always a huge kettle and folks making fresh kettlecorn........I cannot pass by without buying in bulk.
