Kahlua Popcorn

Directions

1. 1
   Keep popcorn in shallow pan in oven to keep warm.
2. 2
   Stir sugar, Kahlua, and vinegar in a pan on stove. Bring to a boil. Add butter. Bring to hard crack stage (300 degrees on a candy thermometer).
3. 3
   Pour over warm popcorn and nuts, stirring to coat.
4. 4
   Let cool.
5. 5
   Store in airtight container. Allegedly will last several weeks. No one has shown enough self-restraint in my house to test this.
