Dried plum is a well-known Hakka local dish at home and abroad. In late autumn and early winter, the mustard in the garden is covered with moss. It has a thick thumb and a bud at the top. Shaped like autumn grapes, crisp and tender. At this time, the village woman picked the cabbage (about 5 inches long) and hung it for a few days. When the leaves become soft, put them in a pot, sprinkle with salt and rub them with your hands. When some juice oozes out, put it into a pottery jar, sprinkle salt layer by layer, and seal the jar mouth with mustard leaves or bamboo shoots. After half a month and twenty days, it was taken out and dried in the sun, and it became a dried plum dish with golden color, salty taste and special fragrance.
