Longmen Pepper Buns gathers charcoal toast, thin crisp pastry, and fresh filling at one takeaway window. The plump pepper bun opens to pork juice, scallion, and gentle pepper beneath golden sesame; sweet crisp cakes and small pies turn the same handmade dough into distinct sweet and savory snacks. Kneading, filling, oven-wall baking, and unloading are visible in line.
Setting and atmosphere:
A former cart has expanded into a front shop and rear workshop with no seating; customers queue under the arcade. Staff divide kneading, filling, sesame, and oven work as three charcoal ovens rotate batches. The line may reach neighboring storefronts but moves quickly. Sesame, pastry, and charcoal aromas overlap, and finished buns move from bench to bag almost without pause.
Location and dining notes:
The address is 新北市三重區龍門路30號1樓, about a four- to five-minute walk from MRT Sanchong Elementary School Station. This is takeaway service; follow the arcade flow and keep neighbors' doors clear. A fresh pepper bun is extremely hot. Vent it with a small bite. Its thin crust softens as juices sit, so eat warm to enjoy the charcoal-crisp base.
Meal highlights:
● Pepper Bun

The plump dough bakes on the charcoal oven wall to a golden, charred base and fragrant sesame top. Beneath a thin crisp shell are pork with balanced fat and long scallion pieces. Juices carry scallion sweetness; black pepper is clear but not aggressively hot. The outer dryness, moist center, tender meat, and crunchy scallion create three textures.
● Sweet Crisp Cake
This flat, elongated cake has thin dough crowded with white sesame and bakes as crisp as a cracker. Maltose melts into a thin amber layer, laying gentle sweetness between pastry sheets instead of flowing heavily. Warm, its aroma is fullest; cool, it retains a clean snap, with sesame, wheat, then mild sweetness.
● Small Savory Pie

The small round pie holds fresh scallion and minced pork fat. As the fat melts, it traps sweet scallion and savoriness inside thin pastry, keeping the center moist. Sesame and crisp edges lead to scallion and richness. Because the filling contains pork fat, it is not a vegetarian scallion cake.
Eat a fresh Pepper Bun first, then compare Sweet Crisp Cake and Small Savory Pie to see one handmade pastry take on three personalities.
Ordering notes
- A fresh Pepper Bun concentrates steam and meat juice; make the first bite small to release heat.
- For a sweet-savory comparison, take both Sweet Crisp Cake and Small Savory Pie; their shapes and fillings differ.
- Service is takeaway. Follow the arcade queue, then find a convenient place to eat.
Longmen is memorable not only for a juicy pepper bun but for the repeated handwork at the bench. Charcoal chars sesame and thin pastry, pork and scallion stay moist, while sweet cakes and small pies branch into brittle sweetness and scallion savoriness. From watching buns filled to hearing thin crust crack in hand, the experience centers on freshness; tasting all three shows how simple ingredients become clear contrasts.
