Sanxing Scallion Baked Flatbread (Congzai Bing)

Baked thin and crispy at Sanxing Market — an oven snack that lets the big scallion's natural fragrance speak for itself

Sanxing Congzai Bing is not the same as cong you bing (scallion pancake) — it is baked in an oven, not pan-fried or deep-fried. A dough packed with generous amounts of Sanxing large scallions is placed in a traditional oven; the result is a thin, crispy crust with a direct, clean scallion fragrance rather than a sharp bite. This is a locally specific form found around Sanxing Market, and the fresh-from-the-oven stall near the Farmers' Association is the most straightforward introduction to what Sanxing scallion can really taste like.

What is Sanxing Congzai Bing

Sanxing Congzai Bing is made from a wheat-flour dough mixed with large sections or finely chopped Sanxing large scallions, then placed into a traditional oven (not a frying pan) and baked at high heat. The crust is thin and layered with a light char, while the interior is soft with pieces of scallion throughout; the scallion fragrance develops and blends into the dough during baking rather than becoming heavy and oily the way deep-fried scallion pancakes do. Sanxing large scallions have thick, plump stalks, a noticeably sweet flavor, and a mild pungency — they are the essential ingredient; versions made with scallions from elsewhere fall noticeably short.

Sanxing Congzai Bing is a snack format specific to the area around Sanxing Market, distinct in cooking method from the 'cong you bing' (pan-fried scallion pancake) found everywhere in Taiwan. The Sanxing Township Farmers' Association's Sanxing scallion promotional materials include Congzai Bing as a representative local scallion product; the Yilan County Tourism website's Sanxing scallion origin introduction also explains it as a snack unique to Sanxing Market. Vendors baking fresh near the Farmers' Association are often local farming households selling their own produce, and quality is directly tied to the freshness of the scallions.

How to eat it like a local
