A signature cocktail is a really easy way to make your holiday party seem fancy, but is actually a really cheap way to come off as swanky. I highly recommend it. It's the secret to every good party.
This is a great one too because the cider can double as a non-alcoholic drink. Put everything out for your guests, teach your chattiest person how to make them, then assign them as the 'bartender' for the night. Enjoy!
