What is Elf spaghetti? It’s a forbiddingly sweet pasta dish topped with any sugary bites from candy to cereal inspired by Buddy the Elf’s morning routine. “We elves must stick to the four main food groups: candy, candy canes, candy corn, and syrup,” the tall elf once said. It’s unlikely the humans could survive on that diet, but it’s doable for an all-day charitable event.

Mario’s Pizza is teaming up with Albuquerque Christian Children’s Home to bring the candied pasta dish to all diners this coming Sunday, November 24. For only $5, customers can create their own gelato “Elf spaghetti” with maple and strawberry syrup, M&M’s and marshmallows. The pizzeria owner Eddie Burgarello will serve up the sweet dishes with two helper elves, Ava and Ameliana Buragrello.

So what’s the pay-off for risking a worth-it tooth cavity? Albuquerque Christian Children’s Home is a long-term foster care that provides physical, psychological, and spiritual care to at-risk children.

For those wanting to eat this sinful dish year-round (perhaps to their Grinchly self)  can visit Miss Ricky’s in Chicago.
