4 c. brown sugar
4 sticks butter
1 c. white Karo syrup
2 tsp. salt
1 tsp. baking soda
2 batches hot air popped popcorn (pick out all old maids)

Combine sugar, butter, Karo, syrup and salt. Boil 5 minutes over medium heat. Stir constantly. Add soda; stir well. Pour at once over popped corn and stir. Pour onto 2 large cookie sheets and place in 225 degree oven for 1 hour. Stir every 15 minutes. Cool and store in airtight containers in cool place. I always add cocktail salted peanuts (4 cups). You can also add other nuts or raisins.
