manufacturing method
Black beans soaked in vinegar are mainly divided into raw black beans and cooked black beans.
Cooked foam: the advantages are quick but the effect is poor, and the effective components are lost. It needs to be kept in the refrigerator.
Practice: Put the black beans into the pot, cook them on medium heat until the skins burst, and then cook them on low heat for about 10 minutes. Put the cooked black beans into a glass bottle and add the original balsamic vinegar. The ratio of the two in the bottle is about 1/3 and 2/3. After cooling, the bottle cap is sealed, and the black beans can be eaten after absorbing vinegar and swelling. After a long time, the film will grow on vinegar and can be thrown away. If the vinegar is cloudy, change it again. Store in a cool place or refrigerator for 10 days before eating.
Foaming: the advantage is effective, but it takes time and can effectively retain nutrients. You can keep it without a refrigerator.
Practice: Wash black beans, remove impurities inside, dry them in a ventilated place, then pour black beans into glass bottles, and then pour the original balsamic vinegar into the bottles. The vinegar overflows the beans, leaving a third of the space in the bottle, leaving enough expansion space for the black beans during soaking. Finally, cover it and put it in a ventilated and cool place for 2 months, and you can eat it. Eat two spoonfuls a day, put a time label on the bottle cap and check the brewing time. .
