The durability of Liubiju for 400 years has a great relationship with its unique production technology.

Due to different auxiliary materials, pickled vegetables can be divided into seven categories: pickled koji, pickled vegetables with sweet sauce, pickled vegetables with yellow sauce, pickled vegetables with sweet sauce, pickled vegetables with yellow sauce and pickled vegetables with sauce.

Liubiju's pickles are so famous, which is inseparable from its fine selection of materials and strict production. The raw materials of Liubiju pickles all have a fixed origin. Yellow sauce and sweet noodle sauce are the main raw materials for pickling pickles. The yellow sauce made by Liu Biju is specially selected from the good soybeans with full grains and high oil content, such as Majuqiao in Runxian County and Yongle Store in Tongxian County, Hebei Province. To make sweet noodle sauce, they buy sticky wheat as the main material from Laishui County, Hebei Province at a high price. To make sugar garlic, you should use six petals of white garlic produced in Changxindian. Sauce-made melon wrapped in sauce is a special "Eight Black" cantaloupes cultivated by xiaohongmen outside Yongdingmen. Lettuce is green lettuce produced by Taiping Bridge outside Guang 'anmen. Such as cucumber, not only requires smooth strips, but also the top flowers with thorns, four to six strips a catty; Small pickled radish also requires four to six pieces a catty. White flour is selected from Laishui County in the west of Beijing, and it is a first-class wheat. This kind of wheat is sticky and must be added by Liubiju.

Liubiju pickles

Fine white flour, which is suitable for making sweet noodle sauce.

When Liubiju makes yellow sauce, first soak the soybeans in warm water and steam them on the drawer. Then mix the soybeans with white flour, crush them on a mill, then crush them, then put the crushed soybeans into a mold, cover them with a clean cloth, and people will go up to show their feet and step on them. Then take it out of the mold, pull it into three strips, cut it into cubes with a knife, put it on a wooden frame, and seal it with foil to promote its fermentation. After fermentation, let the little apprentice constantly use a brush to remove the white brush from the mat foil. It takes about twenty days before the sauce can be made. Put the sauce into a vat, add salt and water, and then soak the hard sauce in water until it is soft. The workers turned the wooden harrow up and down in the vat on time to ferment it again. After a dog day, the yellow sauce was made. The pickles made by Liu Biju with such good sauce are naturally delicious.
