Every Halloween the balls came out.
Boo & her friend Suzy Kidd would band together to make these around Halloween. She literally would make our family brown grocery sack of them.
What you'll need:
4 cups of white sugar
1 1/2 cup water
1 1/2 cup white corn syrup
3t of salt (kosher is better)
1 cup of butter
Boil the above until it darkens - add 3t of vanilla. "4lbs of popcorn = 1 Laundry basket of full popped + uses 2 bunches of syrup"
That's all the card says. I'll assume you take the popped corn and use the boiled mess above as glue.
