If you’ve spent even a moment in Shanghai, you’ve encountered tea eggs ((茶叶蛋, cháyè dàn) pre-boiled eggs that are cracked and re-boiled in tea and spices, usually a mixture of ground cinnamon, star anise, fennel seeds, and cloves. These coffee-colored orbs are the most ubiquitous eats in town, sold everywhere from street stalls to small dives like Zhouli Laoya Fensi, to our go-to, Family Mart.
