Pepper Buns (胡椒餅), or Hu Jiao Bing in Mandarin, are savory baked buns that have become one of Taiwan's most beloved night market staples. These golden-brown buns are characterized by their crispy, flaky exterior and a juicy, heavily peppered pork filling that creates an irresistible combination of textures and flavors.

The origins of Pepper Buns can be traced to Fuzhou, China, but they have become deeply integrated into Taiwanese street food culture. The buns were traditionally baked in cylindrical clay ovens similar to tandoors, a method still used by many vendors today to achieve the signature crispy crust while keeping the filling moist and flavorful.

The magic of Pepper Buns lies in their preparation. The dough is made from flour, water, and yeast, then allowed to proof until it becomes soft and pliable. The filling combines ground pork with an generous amount of black and white pepper, giving the buns their distinctive spicy kick. Green onions add freshness and complexity to the flavor profile. The buns are traditionally baked at very high temperatures, causing the outside to become crispy while steaming the filling to perfection inside.

While the classic pork filling remains the most popular, modern variations have emerged to cater to different tastes. Some vendors offer chicken or beef versions, while others experiment with additional ingredients like mushrooms or Chinese cabbage. The amount of pepper can also be adjusted to suit different spice preferences, though true enthusiasts insist that a proper Pepper Bun should pack a significant pepper punch.

In Taiwan, these buns are primarily enjoyed as a street food, with vendors often drawing long queues at night markets. They're best eaten fresh and hot, right off the oven, when the contrast between the crispy exterior and juicy interior is at its peak. Some people enjoy them with additional condiments like soy sauce or hot sauce, though purists prefer them as is.

From a nutritional standpoint, Pepper Buns are relatively balanced with protein from the pork and carbohydrates from the dough. However, they can be high in sodium and fat, particularly if consumed as part of a regular diet. The black pepper content may have some health benefits, as it's known to aid digestion and has antioxidant properties. Those with gluten sensitivities should note that the buns contain wheat flour. It's also worth mentioning that these buns are typically quite hot when served, so careful eating is advised to avoid burning your mouth on the steaming filling.
