This is Natalie's recipe:
2/3 cup sugar
1 cup Karo syrup
1 cup crunchy or plain peanut butter
2 tsp vanilla
1 cup popcorn kernels
Pop popcorn and put in large bowl. Remove unpopped kernels. Bring sugar and syrup to a boil. Don't overcook it as it will crystallize. Remove from heat and add peanut butter and vanilla. Pour over popped popcorn and mix.
