I am making several different dessert coated popcorn and wanted to know how I can make it stay fresh for at least a week, with it being good for 2-3 weeks. For example snickers popcorn: unsalted butter, light corn syrup, brown sugar, salt, baking soda, vanilla extract, chopped Snickers candy bars, chopped salted pretzel sticks, and mixed nuts.
Other popcorn such as caramel nutella and cookies & cream popcorn. All three will be baked in the oven to make it crisp.
I am making them for myself and batches for my family in Wisconsin and New Jersey (I'm from Georgia).
What would be the best way to ship these off so it stays fresh? USPS typically takes 2 days to ship. Popcorn companies ship there's off in plastic bags or tins. Should I stick with that or are there other options? Most family members want to get their jobs to place orders for my popcorn, but I haven't accepted it yet as I'm not sure how I can ship it to give them a great first impression. So this could become a side gig for the holidays. If anyone has some solid advice for how I should proceed please do share!
