If you’re set on serving a main dish, fish and chips will do the trick. Or offer hot dogs and call them Salty Dogs. Just serving snacks? Stick to the maritime theme and fill bowls with Chips Ahoy, Swedish Fish, Goldfish crackers, and Pirate’s Booty.
Create a “dessert island” and serve Treasure Hunt Cake (shown), which guests can bite into in hopes of finding hidden treasure (read: gummy candies). The first pirate-in-training to bite into a candy receives a prize, like a plastic bead necklace ($10 for 48, orientaltrading.com). Give the remainder out as p-ARR-ting gifts.
