1 cube butter
1 cup karo syrup
2 2/3 cups brown sugar
In a heavy pan melt butter and coat sides of pan, then add karo and brown sugar. Over medium-high to high heat bring to a boil, stirring constantly.
As soon as it boils add:
1 can Eagle brand sweetened condensed milk
Stir well, turn down heat (medium to medium high), so that it keeps boiling but doesn't scorch. Cook 5 minutes, stirring constantly.
Remove from heat and stir in:
1 tsp vanillaPour over 3 gallons of popcorn
***I put the popcorn in a paper bag and then add the carmel. Close the top and start to SHAKE, SHAKE, SHAKE. By putting it in a paper bag, you can move the popcorn around without getting burned.
