Dessert, in the Form of an Avocado

Giacomo d’Alessandro with some of his frozen avocado creations at Polosud, his gelateria in the Little Italy neighborhood of New York on Oct. 12, 2018. He fills empty avocado shells with lush, creamy and lemony vegan frozen avocado purée, while a scooplet of a contrasting flavor, like hazelnut or coffee, simulates the pit.
