Baiji Niangao is located on the first floor of the Niujie Muslim Market at No. 5 Niujie in Xicheng District, run by Mr. Bai, a Hui Muslim, making the shop fully halal from start to finish — traditional lard is replaced with vegetable oil in the sweet red bean filling. The rice cakes are made fresh daily in front of customers: steamed glutinous rice is spread across a wooden counter, topped with sweetened red bean paste, and carefully rolled up. Popular varieties include lü da gun (rolling donkey rice cake), huangmi niangao (sweet sticky millet cake), and sesame-wrapped sticky rice rolls. The sweets are sold by weight and made in limited daily batches, since they don't stay fresh past the day they're made. The shop is an authentic stop for tasting traditional Hui sweets in the heart of Beijing's Muslim quarter.
