It is a custom in some parts of northern China to soak Laba garlic in Laba. Laba garlic is turquoise, so there is a saying of "jade and jade Laba garlic". The raw materials and production methods of Laba garlic are extremely simple, and all that is needed is rice vinegar and garlic. Seal the peeled garlic cloves in a small mouth container, soak them in vinegar and put them in a cool place. When it is opened and taken out, garlic turns from white to green.
