1Mix the popcorn and nuts. Place in a large bowl that has been buttered (to prevent sticking).
2Mix sugar, margarine and Karo syrup in a heavy saucepan. Bring to a boil and boil for 6 to 10 minutes until it reaches soft ball stage on a candy thermometer. Remove from heat and add vanilla.
3Pour syrup over popcorn mixture and stir well to coat evenly. Spread on a cookie sheet to cool and then break up into bite sized pieces.
