For those of you who couldn't go Trick-or-Treating to Grandma Arlene Koyle's, here is her recipe:
Grandma said she uses Light Karo and REAL butter (and no peanuts)
6 quarts (24 cups) of popcorn separated from kernels
1 cup salted peanuts (optional)
1 cube butter
1 cup Karo (dark or light) or honey
2 cups brown sugar
Bring last three ingredients to a bubbling and pour over popcorn. Mix well with nuts. Form into balls with buttered hands or let cool and pull into chunks.
