蔥油餅Scallion Pancake

A traditional scallion pancake starts with a flour-and-water dough (many recipes scald part of the flour with boiling water for a softer crumb). After resting, it is rolled thin, brushed with oil, sprinkled with salt and plenty of chopped scallion, rolled into a log, coiled into a spiral and pressed flat before frying in a little oil until golden on both sides. Some shops fry 'half pan, half deep' (半煎半炸) with more oil for an extra-crisp crust, and a few roll the dough out to order.

The 蔥抓餅 takes a different route: it is all about layers, and the hot pancake is beaten and scrunched with spatulas or hands to loosen them. The scallion pancake proper is fried in more oil, crisp outside and chewy within, and relies on its scallion and oil aroma rather than on being scrunched. At the stall you can add egg, Taiwan basil, cheese, ham or bacon, then soy paste, pepper or chili sauce. According to Chinese Wikipedia, many shops cook ready-made frozen dough sheets to order.

The scallion pancake belongs to the wheat-eating north, and in rice-centered Taiwan it spread mainly after the war. An estimated 900,000 to 1.1 million people moved from the mainland between 1945 and 1955, bringing their home cooking with them, while US aid wheat and flour pushed Taiwan toward wheat-based foods and fed a domestic milling industry. An article in the Taiwan Gazette says a wheat-products promotion council set up in 1962 ran centers in Taichung, Taipei and elsewhere that taught Chinese wheat snacks, including xiaolongbao and scallion pancakes. The council itself is also documented by FoodNEXT (founded 28 April 1962, with 苗育秀 as founder) and by U.S. Wheat Associates (it set up a baking school in Taipei), though neither mentions teaching scallion pancakes.

Regional versions have their own stories. An entry in the National Cultural Memory Bank, filed by the Lienchiang County Culture Bureau and citing a 2017 Taoyuan City survey of Matsu migrants, records that many soldiers stationed on Matsu came from the north and kneaded local wild scallions into dough, rolling it into big thin sheets with an old liquor bottle before frying. Later, Matsu natives sold the pancakes in Taiwan for a living and even supplied manufacturers. Yilan is known for Sanxing scallions: Taiwan Business TOPICS says Yilan's scallion-oil pancakes are known islandwide, and the official Luodong tourism site lists scallion pancakes among that night market's popular snacks, although Chinese Wikipedia lists Yilan's 蔥餅 as a separate item and notes it is not a 蔥油餅, so how the two relate is not settled. The flaky 蔥抓餅 has more legend than paper trail: Chinese Wikipedia and a Global Views column both link it to Shandong's 油旋 (a coiled fried dough), the former citing only a 2018 Sohu food article about Jinan's 油旋 and the latter giving no sources, and the columnist, who traveled to Tianjin and was told the snack there is 'Taiwanese hand-grab pancake', guessed that the 'Tianjin' in the Taiwanese shop name was a mix-up over the origin. That it crossed to mainland China as 手抓餅 around 2005 rests on a single uncited line in Chinese Wikipedia.
