I think, if you are into the gore-food, you could probably pick any of the traditional "Halloween"-themed food even though you are camping - it may just take some extra work on the campsite to set it all up.
Do a trail mix station where people can make their own mix. Include pretzels, chex, peanuts, m&ms, etc. I always do some type of food station at my parties because I find people really enjoy them! I did a make your own caramel apple station last year and am doing a popcorn station this year Other than that i think hot dogs, s'mores, baked beans, corn on the cob, and chips. That's what we always have when we go camping!
You've probably seen Pirates Booty or FritoLay's Chesters Puffs? Well, make Goblin Booger's.
Open and pour corn PUFFS into large container. Next, pour caramel sauce over the puffs and mix til well coated. THEN, lay it out on a cookie sheet at 200. Bake for 46 minutes turning the mix every 15 minutes. Remove, cool and package.
Candy Corn Mix
2 cups Candy Corn
2 cups Salted Peanuts
1. Mix equal parts of candy corn and peanuts together in an airtight container.
2. For best results allow to sit for 24 hours before eating.
Cream cheese (16 oz)
Sour cream (16 oz)
16 oz cream cheese
Cheddar cheese (2 c)
16 oz sour cream
Bacon - 6-8 slices of bacon
2 cups shredded cheddar cheese
Mix together, put more cheddar cheese on the top. Bake at 350 for 20 minutes or until the cheese bubbles
I like the ghastly, gaggy presentation. Labels are made that remain the food items. I think this year each guest will get a chance to do the same with their dishes brought. AND, then all the guests will rate the one that is ghastliest yet yummiest.
I have a lot of foods on my pinterest board @gastronomical delights.
