Seperate popcorn from unpopped pop corn. Place in a large aluminum foil pan
Heat syrup, sugar, vanilla, butter and salt until boiling. Stirring so sugar doesn't burn or stick. When syrup reaches a full boil add peanuts. let mixture return to a full boil adding baking soda. Mixture will foam but it's suppose to do this. It will look very creamy. Let peanuts he up throughly then remove from heat and pour over pop corn. Stirring making sure it is mixed well. Place in oven at 250 degrees for 1 hour. Stirring mixture every 15 min. for the hour. That means you will stir your popcorn 4 times in an hour. Each time stirring well to coat each popcorn with syrup and peanuts.(I use a large spatula to stil with), Let cool in aluminum foil pan until dry to touch and break and place in ziploc bags. ENJOY!!!
