托福阅读背景知识：风靡美国的煎饼
Jian bing, a form of grilled savory crepe with stuffing, is a popular dish in North China. The mung-bean-and-millet crepe is often made on a well-heated pan. Freshly scrambled egg, pickled vegetables, scallions, cilantro, black bean paste, chili sauce and a crispy fried crackers (the secret that adds a crunch to the crepe) are added on the crepe and rolled up. Often sold by street vendors, Jian bing is a popular choice for breakfast for on-the-go commuters.
煎饼，是一种包有内馅儿的咸味煎薄饼，它在中国北方广受欢迎。在烧得滚热的案板上，摊开绿豆和小米面糊烙成面饼，在面饼上打一个鸡蛋，撒上泡菜、大葱、香菜，涂上豆瓣酱、辣椒酱，然后放上一块薄脆(让煎饼酥脆的秘密)，再卷起来。煎饼通常是大街小巷的小贩在卖，它是许多赶着上班的通勤族最爱的早餐。
Alisa Grandy, the owner of Bing Mi!, fell in love with the snack when she returned to Portland from her trip in China.
艾丽莎•格兰迪是Bing Mi的店主，在她从中国旅游回到波特兰以后，她对煎饼的爱就一发不可收拾。
"When she got back from China, that's all she would talk about," says her husband Neal. Grandy spent months perfecting the right mix of ingredients to recreate the exact taste she enjoyed in China. Six months later, the couple opened a store. Business is good, as they've already got two crepe-makers on back order.
她的丈夫尼尔称“自打她从中国回来以后，她成天都在谈论煎饼”。后来格兰迪花了好几个月，专门研究煎饼的原料和配方，以复制她在中国尝过的那种味道。六个月后，夫妇俩开了家店。生意非常红火，两个煎饼师傅都忙不过来。
Bing Mi! sells a piece of jian bing for $6. In fact, it is the only item that they sell. According to Grandy's husband, Chinese customers nostalgic for the taste of home have given their compliments.
Bing Mi!的煎饼每个售价6美元。事实上，他们只卖煎饼。格兰迪的丈夫称，因思乡而来品尝故乡味道的中国顾客称赞了他们做的煎饼。
