You can make any cocktail, your signature Halloween cocktail, simply by adding gummy wax teeth or licorice squiggly worms to your concoctions.
Find fun items at a party store or candy store. If the items are not edible—such as a fake eyeball—make sure your guests are aware or highlight them by putting them through a cocktail stirrer or Halloween-styled umbrella.
Take a regular drink recipe and add the fake items as decoration.
You can also serve a mulled cider and put a green apple slice on the glass for a decorative autumn-style look. Set up a few small pumpkins on your home bar and buy some Halloween-themed napkins.
Add candy corn or a cute decoration to any cocktail to make it a Halloween specialty. This photo is from Cosmopolitan.
