In ancient China, during the Cold Food Festival, people generally didn't make a fire to cook, but only ate cold food. Cold food is prepared in advance and does not need heating. Among them, wormwood Baba is one of them. It is made by mixing wormwood juice, a kind of wormwood only found around Tomb-Sweeping Day, with glutinous rice (or glutinous rice and flour) in proportion, kneading it evenly by hand, and then wrapping it in different fillings for steaming.
In China, there are similar foods and cakes in many places, and the production method is similar to that of wormwood Baba, which was made of glutinous rice or glutinous rice before and after Tomb-Sweeping Day. In Guangdong and Taiwan Province provinces, it is called Aizan, in Jiangxi, Ai Guo, in southern Fujian and Chaoshan, and in Guangfu, it is usually called Ai Bing.
The wormwood Baba tastes sweet, soft and delicious, with the aroma of wormwood leaves. The appearance is dark green, the stuffing inside is bean paste, and the entrance has a faint fragrance of wormwood leaves.
