蟹壳黄Crab Shell Pastry (Xie Ke Huang): Shanghai’s Flaky Street Food That’s Even Tastier Than Crab
When wandering through the old lanes of Shanghai, you might suddenly catch a heavenly aroma—a mix of toasted sesame and savory lard. Follow your nose, and you’ll likely find a small oven at a street corner baking rows of golden pastries that look just like crab shells. This is the legendary Crab Shell Pastry (Xiè Kè Huáng), a street snack Shanghainese people have loved for nearly a century. Despite its name, there’s no crab inside—its magic lies in 128 layers of flaky crust and juicy fillings that burst with flavor in every bite.
1. Origins: A Blend of East and West
Crab Shell Pastry was born in 1920s Shanghai, when local pastry chefs created a baked snack that resembled a crab’s golden shell. Combining traditional Chinese pastry skills with Western baking techniques, it became one of the most iconic Haipai (Shanghai-style) pastries—a proud symbol of the city’s culinary creativity.
2. A Cultural Icon of Everyday Life
For locals, Crab Shell Pastry is more than just food—it’s a morning ritual. At dawn, you’ll see Shanghainese aunties and uncles lining up to buy a bag of these hot, flaky pastries fresh from the oven. It’s not a luxury dish, but rather a symbol of Shanghai’s everyday warmth: affordable, satisfying, and full of soul.
3. Ingredients: Layers of Flavor
- Crispy Outer Shell – Made from oil-based dough that’s folded and rolled repeatedly into 128 ultra-thin layers, topped with white sesame seeds that roast into golden crunchiness.
- Fillings – Two delicious categories:
- Savory: Classic scallion oil with lard and salt, or juicy pork filling.
- Sweet: White sugar with osmanthus, or smooth red bean paste.
- The Secret – Baking in a traditional barrel oven to achieve the perfect flaky texture.
4. How It’s Made: The Craft Behind the Crisp
- Folding the Dough – Layer upon layer, rolled and folded to create the flaky texture.
- Sealing the Filling – Wrapped into a round shape, brushed with sugar water, and pressed into sesame seeds.
- Oven Magic – Stuck onto the inner walls of a barrel oven, baked for 10 minutes while turned by hand until the pastry puffs and turns golden brown.
5. Flavor & Texture: A Bite of Heave
The first bite is pure crunch—crispy sesame flakes breaking apart in your mouth. Then comes the filling: hot scallion oil bursting with aroma, or sweet molten sugar seeping through the layers. Eating it properly means catching the falling flakes with your hands—messy, but that’s part of the fun!
🍽️ How to Eat Crab Shell Pastry
