Tucked within the alleys of old Shanghai and still found sizzling on street corners and in traditional bakeries, Xie Ke Huang, or Crab Shell Cake, is one of the city’s most beloved snacks. Despite its modest appearance, this flaky pastry offers a rich blend of culture, history, and flavor. For those discovering Shanghai through its food, this golden, sesame-covered delight is a perfect bite-sized introduction to the city’s enduring traditions.
What Is Crab Shell Cake?
Contrary to what the name might suggest, Xie Ke Huang contains no crab. It gets its name from its appearance—golden-brown, round, and slightly convex, with a crisp, layered surface speckled with toasted sesame seeds that resembles the back of a crab shell. When freshly baked, the pastry has a warm, comforting aroma and a delicate crunch that gives way to a soft, flavorful filling.
Traditional fillings vary and include:
-
🫘 Red bean paste – sweet and earthy
-
🍖 Savory minced pork – juicy and aromatic
-
🌱 Spring onion and oil – fragrant and light
-
🥜 Sweetened mashed black sesame – nutty and rich
Each version provides a slightly different experience, but all are encased in a carefully crafted pastry that speaks to Shanghai’s culinary finesse.
Historical Roots
The origins of Xie Ke Huang date back to the late Qing Dynasty, when street vendors in old Shanghai began selling these pastries in local markets. They quickly gained popularity among workers and scholars for being affordable, portable, and satisfying.
Its production techniques were influenced by both northern-style baked buns and southern-style pastries, reflecting Shanghai’s unique geographical position as a cultural and economic hub. Over time, the snack became synonymous with authentic local flavor and was often included in celebratory feasts or family gatherings.
In the early 20th century, as Shanghai emerged as a cosmopolitan city, Xie Ke Huang found its way into tea houses and old-style pastry shops, gaining a reputation not just for taste but for its symbolic connection to home and heritage.
Craftsmanship and Cultural Value
What sets Xie Ke Huang apart is the artisanal skill required to perfect it. The pastry dough is layered and folded multiple times, often incorporating lard or oil to create that signature flakiness. Each cake is then brushed with egg wash and generously coated with sesame seeds before baking until golden.
This seemingly simple snack requires precision in every step—temperature control, dough elasticity, and careful baking—to achieve the perfect combination of crispness and tenderness.
Beyond the culinary technique, Crab Shell Cake reflects key aspects of Shanghai culture:
