Soak the dried beans in plenty of water overnight, then drain.

Put the drained beans in a pot with fresh water, add salt, and simmer over low heat until soft.

Drain the boiled beans and fill sterilized jars with them, then add lightly salted boiling water on top.

Close the lids and sterilize the jars by boiling them in a pot of water for ten minutes.

Let the jars cool completely, then store in a cool, dark place.
