10 cups popped popcorn
2 cups packed brown sugar
1/2 cup light corn syrup
1 tsp. salt
two sticks butter
1/2 tsp. baking soda
1/8 tsp. cream of tartar
1 tsp. vanilla
Preheat oven to 250F
Line 2 baking sheets with parchment paper. Spread the popcorn over both sheets and add a bit of salt to each tray.
In a medium sauce pan, melt butter. Add sugar and syrup. Stir constantly. Bring to a boil and let cook for 5 minutes, continue to stir. Remove from heat and immediately add vanilla, baking soda and cream of tartar.
Pour caramel over the popcorn and toss to coat. Bake for one hour, stirring every 15 minutes.
Cool completely and break into pieces. Enjoy!
Note – this makes a terrific gift packed into decorative tins or in goodie bags tied with ribbon!
