Dajia Butter Pastry (Nai You Su Bing)

A flaky pastry born in the incense smoke of Zhenlangong Temple — Dajia's signature butter souvenir
📍 Taichung · Zhenlan Temple, Dajia District⭐ Specialty · Dessert🔖 Butter filling / Flaky pastry / Dajia specialty

The aroma of Dajia butter pastry drifts from the Zhenlan Temple commercial district all the way to souvenir shelves across Taiwan. The pastry shell is made by repeatedly folding lard and flour to build up flaky layers; the filling is a butter-based sweet paste baked at high heat until the surface turns golden and crackles into layers. One bite sends flakes scattering and fills the mouth with a rich butter fragrance. This is neither taro puff nor sun cake — it is a distinct pastry category unique to Dajia, more direct and expressive in both aroma and texture.

What is Dajia Butter Pastry

Butter pastry is made from two types of dough — oil-skin and oil-paste — repeatedly layered and folded to create a flaky shell. The filling is a mixture of butter and sugar. After shaping, the pastry is baked at medium-high heat. The finished shell forms multiple thin, crispy layers with a golden color and a noticeably crumbly feel when pressed. The filling is rich in butter fragrance and moderate in sweetness, somewhere between a butter puff and a custard bun. The pastry keeps at room temperature and is well suited as a gift. Yu Zhen Xiang is the most established and representative brand for Dajia butter pastry.

Zhenlan Temple in Dajia is one of Taiwan's most important centers of Mazu worship. The annual Mazu pilgrimage procession draws enormous numbers of devotees and tourists, fueling a thriving pastry industry in Dajia. Butter pastry is closely linked to the religious ritual culture surrounding the temple — production surges during the pilgrimage season, and devotees from across Taiwan use the occasion to taste the flavors of Dajia. Brands such as Yu Zhen Xiang have achieved island-wide distribution and can be found in major department stores and airport duty-free shops, though buying locally in Dajia still gives access to the freshest same-day batches.

How to eat it the local way

🌡️
Freshly baked is bestButter pastry keeps at room temperature for several days, but the shell is crispiest and the butter fragrance most intense straight from the oven. When buying in Dajia, ask about that day's baking schedule and choose the freshest batch available.
Pair with hot teaButter pastry is fairly sweet and rich in fat. Unsweetened oolong tea or a light green tea works best to cut through the richness and bring out the layered texture of the shell.
🛍️
Buy several boxesPastry purchased in Dajia is fresher than what you find at outlets elsewhere, and occasional store-exclusive flavors are an extra draw. Single boxes are relatively poor value — two to three boxes at once is the practical choice for sharing with family and friends.
📦
Handle with careThe flaky shell breaks easily. After purchase, keep the box flat when carrying and avoid stacking heavy items on top or leaving it upside down for long. For gift purposes, choose a boxed set with proper packaging to protect against damage in transit.

Local knowledge

Context

  • Yu Zhen Xiang is the representative brand for Dajia butter pastry, with island-wide distribution and sales points in department stores and airports.
  • Dajia butter pastry is closely tied to the Dajia Mazu pilgrimage culture. The lunar third month pilgrimage season is the product's peak period, with significant increases in both production and sales volume.
  • Dajia District is known for 'Dajia pastries.' Butter pastry is an independent category — distinct from taro puff and sun cake — with clear category identity.

Things to know before you go

  • Dajia butter pastry is not taro puff. The two look similar on the outside but the filling and texture are entirely different — check the filling description before buying to avoid confusion.
  • During the Mazu pilgrimage (lunar third month), Dajia draws enormous crowds. Parking near the Zhenlan Temple commercial district becomes very difficult; taking the TRA train to Dajia Station and walking is the recommended approach.
  • Some butter pastries sold through online channels are not made in Dajia. For gift purchases, verify the brand and place of origin.
