Nai Nai is making her favorite dumplings for Lili. Lili walks readers through each step, until the final one when Nai Nai realizes that she’s run out of cabbage! She sends Lili up to the 6th floor to see if the Polish grandma (Babcia) has any cabbage. This is where the story gets even more interesting.
It turns out that Babcia does have cabbage, but she’s also missing an ingredient for the pierogies she’s making. Lili’s one errand becomes several as she shuttles between a Jamaican grandma (Granma), a Pakistani grandma (Teta), an Italian grandma (Nonna), and a Latina grandma (Abuela) — all in Nai Nai’s building picking up and dropping off ingredients. Will Nai Nai finally make her dumplings?
