PHILADELPHIA – Rita’s Italian Ice is turning up the sour with a brand new flavor.

The “Sour Blue Pucker” features Trolli octopus gummies and is topped with “sour dust.”

Adventurous dessert seekers can get it as a gelati or a Blendini.

The flavor celebrates Rita’s 20-year partnership with Alex’s Lemonade Stand. The nonprofit raises money to help fight childhood cancer.
