Pork blood sausage scallion roll is a snack exclusive to Luodong Night Market, made by rolling glutinous-rice pork blood sausage with Yilan's Sanxing scallion in a thin flatbread; the result is savory-sweet and richly fragrant with scallion, a recipe the old A-Zao Bo stall has kept for decades.
According to Taiwan's Agriculture Knowledge Portal, Sanxing Township in Yilan grows scallions on about 250 hectares, accounting for roughly 60% of Yilan County's total scallion output. Sanxing scallions have unusually long white stalks — 20 to 25 cm — with low fiber and a sweet, mild taste, which is why they are prized island-wide and often used to elevate local street snacks.
What is Pork Blood Sausage Scallion Roll?
Pork blood sausage is made by filling pork intestine with glutinous rice, pig blood, and seasonings, then steaming it. Sliced into sections, it has a springy, chewy glutinous rice texture with the characteristic iron-sweet richness of pork blood. The scallion roll component pairs sections of Sanxing scallion with the pork blood sausage, wraps them in thin flatbread or spring roll skin, drizzles with sauce, rolls it tightly, and cuts it into pieces. Sanxing scallions have large, thick stalks and a strong aroma; their sharpness contrasts with the savory-sweetness of the blood sausage. The scallion is as much a star as the sausage, and the quantity of scallion is visibly greater than in typical scallion rolls.
This street food is a locally evolved version specific to Luodong Night Market, combining Yilan's most famous agricultural product — Sanxing scallion — with traditional pork blood sausage to form a combination supplied exclusively by Luodong Night Market vendors. A-Zao Bo and other established stall operators can be looked up in the Luodong Township Office's night market vendor registry. The Yilan County Tourism Bureau's night market food guides have long included this item, and several local food blogs have documented it in detail.
