Yellow soybean paste is used most notably in the noodle dish called ''zhajiang mian'' . In this dish, the yellow soybean paste is fried together with ground pork, then poured over the top of thick wheat flour noodles. Unlike sweet noodle sauce, yellow soybean paste is salty rather than sweet.
Yellow soybean paste is widely available in China, as well as in overseas, and comes in plastic packages. Three of the most prominent companies producing yellow soybean paste are the Liubiju company and the Wangzhihe company, both of Beijing; and the Tianyuan company of the Zhejiang province.
In recent years, a new form of yellow soybean paste, called "dry yellow soybean paste" , has been developed, and is widely available in plastic packages. Its texture is drier than that of regular yellow soybean paste , allowing for easier transportation and keeping. Dry yellow soybean paste is used in a similar manner as regular yellow soybean paste, but, when using the dry form, water is first added to dilute it, and then it is added to the dish; if it is added directly to a dish, the amount of water added to the dish should be adjusted accordingly.
